Sprite upscaler

Models that use the "old" esrgan architecture. You can also use tools that wrap around one of them, like IEU from Honh. In computer graphics and digital imaging, image scaling refers to the resizing of a digital image. In video technology, the magnification of digital material is known as upscaling or resolution enhancement. Drawing is a form of visual art in which a person uses various drawing instruments to mark paper or another two-dimensional medium.

Instruments include graphite pencils, pen and ink, various kinds of paints, inked brushes, colored pencils, crayons, charcoal, chalk, pastels, various kinds of erasers, markers, styluses, and various metals such as silverpoint. Digital drawing is the act of using a computer to draw. Common methods of digital drawing include a stylus or finger on a touchscreen device, stylus- or finger-to-touchpad, or in some cases, a mouse.

There are many digital art programs and devices. It has oil colour based shading with sharp lines. Only PNGs were used, mainly with brush strokes and gradients. Texturised images avoided as much as possible. If too generative, tone down by interpolating with a softer model. De-Toon, is a model that does the opposite of tooning an image. It takes toon style shading and detail, and attempts to make it realistic.

Its very sensitive, and can be used on small sprites, to large images. Also included is a alt version, which is less sharp. DigiPaint is a digital art upscaler designed to take brush strokes into account, based off of the Falcoon Fanart model. High Definition digital art from Deviant Art was used, reducing the LR training to 32 colours so the training images looked pixelised.

Can be used with other environments such as manga or digital art. FireAlpha is an attempt to create a 4 channel model that handles transparency without splitting and upscaling separately. The Comic Book model was trained using stills from the film spiderman into the spiderverse, has a comic book crosshatch shading effect to the images.

DigitalFrames 1. This model is highly sensitive to grain and other type of noise so if an improper input image is feed, the results can have severe blobs of noise if the source image has any type of grain, even if barely noticeable. DigitalFrames 2. It has a reduced sensitivity to noise which reduces the blobs of noise phenomena.

Overall it's a big leap from 1. But as the title says it's the most aggressive version of DF. Does it's best on animation with little to no textures. If your piece has few textures or none at all, 2. The SpongeBob model was trained for the purpose of upscaling Battle for Bikini Bottom's textures, but it works well for upscaling scenes from the show as well.

It was initially trained on the clean downscaled images but later jpeg, quantization, dithering, and gaussian blur were added to the LR OTF options to help it upscale the textures better. Spongebob v6 is ideally a lot sharper and cleaner, but Joey's still not sure if it works better than the old one.

It still seems to be better in many cases. Spongebob v6 De-Quantize is for de-quantizing as well as upscaling. The results are pretty blurry but it works decently enough. Spongebob v6 Deblur was created as Joey wasn't entirely happy with the main Spongebob v6 model. It was trained with blurring OTF options and two different downscale types.Eduardo Oriz and Mike GeigMarch 13, Retro games with simple mechanics and pixelated graphics can evoke fond memories for veteran gamers, while also being approachable to younger audiences.

Get our sample project and follow along! Mega Cat Studiosout of Pittsburgh, Pennsylvania, has turned the creation of highly accurate retro games into an art form. So much so, in fact, that several of their titles can also be acquired in cartridge form and played on retro consoles like the Sega Genesis. Recent additions to the Unity workflows have made it a well-suited environment for creating your retro games.

Additionally, you can use the new Pixel Perfect Camera component to achieve consistent pixel-based motion and visuals. You can even go so far as to use the Post Processing Stack to add all sorts of cool retro screen effects. Before any of this work can be done, however, your assets will need to be imported and set up correctly. Our assets first need a correct configuration to be crisp and clear. If compression is used, the data of the image will be compressed which results in some loss of accuracy to the original.

This is important to note, as it can cause some pixels to change color, possibly resulting in a change to the overall color palette itself. The fewer colors and the smaller your sprite, the greater the visual difference compression causes. Another thing to be aware of is the Max Size setting for the image in the Inspector. This will usually result in some loss of quality and cause the image to become blurry.

Since some hardware will not properly support textures over on either axis, it is a good idea to try to stay within that limit. Above, is a sprite from a spritesheet that was on one axis with max size set at As you can see, increasing the Max Size property to allows the image to be sized appropriately and avoid a loss of quality.

If the sprite were to not pivot from a pixel exactly, we would lose pixel-perfectness. Pivots can be set for sprites in the Sprite Editor, which can be opened from the Inspector when you have a sprite asset selected.

A pixel-perfect result will look clean and crisp. Select 2D Pixel Perfect from the list on the left, and select install on the top right of the window.

To add it, go to your main camera and add the Pixel Perfect Camera component to it. If the Pixel Perfect Camera component option is not there, follow the previously stated instructions to first import it into the project. The component will display helpful messages in the game view explaining if the display is not pixel-perfect at any given resolution.

Now, you can go through each setting to see what they do and how they affect the look of your game! Original not rotated 2. Without Upscale Render Texture rotated 45 degrees, pixel-perfectness is lost as pixel size varies on diagonal edges 3. With Upscale Render Texture rotated 45 degrees, pixel-perfectness is maintained as all pixels are the same size, but the sprite is less accurate looking compared to the original. Pixel Snapping disabled.

With our background at position 0, 0 and our character sprite at 1.If you are asking questions about a project, either find that project's thread, or start a thread in the General section instead.

Got a cool project idea but nothing else? Put it in the project ideas thread instead! Projects for any Doom-based engine especially 3DGE are perfectly acceptable here too.

Please read the full rules for more details. It's my private project and I'm working on it in my free time. The first version will be available for download in late March or early April.

I will inform you about the current status. You do not have the required permissions to view the files attached to this post.

Good luck, here's hoping this one gets closer to completion than the many many many previous attempts. But seriously though, be aware than this is a massive undertaking and you are far from the being the first to attempt it. What little you have so far does look nice though.

Best of luck. Yes I know about sprites situation. Many packs but many ufinished and not all look good. I am big doom fan and I how many other people want play little modern looking doom. Good sprites are not much. I want made especially frequently used sprites not ALL. Not weapons and not monsters. I have actually done 14 sprites and some are with animation. This is many many hours work. I am not professional but I want made sprites and textures so close original how is possible from me.

Some of these look really nice.

The rocket looks a bit odd though. It looks like an upscale that has been retouched to look sharper and the finsare different lengths the one on the front is much shorter than the side ones.

Wings are with different size also on original sprite. Someone know what is written under ammo on original sprite? Edit There is nothing. I think this is only line. I have done only this one for D64 but later I planned more for this game. Looks blurry.It makes a pretty good companion wad.

The Verge. I finally used Nvidia's solution it took some time to be in the beta! Also the contrast is changed, bright details are brighter, and dark one are darker too, this had to be cleaned as well by removing them and leting the original texture color appear.

The clean isn't perfect but a first alpha release stage has been reached and I can test it ingame I'm sure a lot of work is left to go as these patches cause texture alignment to go out of sync.

The same would go for LMP files, really, outside of using some editors that make arbitrary assumptions when converting images. As explained here. HD sprites is the one thing we haven't really had before. Thanks for the help DragonFly and Gez : Spectre01 : it works pretty well on sprites too :I wanted to release everything at once, but well, I need the textures to work, finishing this will teach me things that will be usefull when doing sprites.

This looks very interesting!

Doing an HD Remake the Right Way

There is a definite "style" to how it extrapolates detail, but things like door texture and the Icon of Sin part look really good. Definitely want to see this in action. Some of the textures appear larger than they are supposed to but other than that, it looks really good!

Anyway, I was serious about when I said it would work well with Smooth Doom. Upscaled Doom textures combined with upscaled smooth sprites. It would be like an official Doom remaster!

I would like to see a 4x, 8x version too, just out of curiosity. It it does not take too much effort of course. Are there any instructions on how to fix this? Doom2 minor sprite fixing project seems also to be taken into consideration. Linguica : I'm still fighting with my files to make this work worrectly, with no success :.

First sprite test : the zombie Sources are available on google drive. These are very impressive! They made need a little tweaking, but it's a great start. Just saying. I found that we can have some results even with online converter like waifu2x but only in graphics based on simple shapes and lines like Cacodeamon for example. Do not forget that Romero had an archive released that had a full 8 rotations for the zombieman and shotgunner not that long ago. Yeah, we have an Oblidge, but Oblidge is a tool, not an AI.

It looks very cool but I still hope you plan to release pixelated versions of the assets. I think the chunky pixels are a big part of what makes Doom Doom. You need to be a member in order to leave a comment. Sign up for a new account in our community.

Posted February 2, edited.This can be compared to a sheet of paper on which you draw the individual frames for animated object s. Depending on the framework, this may also be known as a sprite sheet, texture atlas, or image map. For more information on image sheets, see the Image Sheets guide. Pictured below is a sample image sheet for a running cat, titled sprites-cat-running. This sheet consists of eight "frames" in a specifically ordered sequence.

To configure this image sheet in Corona, first set up an indexed table with various properties. In this table, width and height specify the pixel dimensions of each individual frame.

Since there are 4 frames across and the image sheet is pixels in overall width, each frame is pixels wide. Similarly, since there are 2 rows and the sheet is pixels in overall height, each frame is pixels tall. The next parameter, numFramesspecifies how many total frames exist on the image sheet. Since there are clearly 8 frames of animation for the running cat, this value should be set to 8. Once this table of options is declared, creating the image sheet is accomplished via the graphics.

The image sheet file name should be passed as the first parameter and the options table as the second parameter:. All animated sprites require at least one named sequence declared as either consecutive frames or non-consecutive frames. The most basic sequence is consecutive frames. This accepts a sequence name, the starting frame index, the frame count, an optional time duration for the animation, and two optional looping parameters.

The name parameter is required and can be used to set the sprite to this sequence. The start and count parameters are also required — since the running cat has 8 total frames, the start frame can be set to 1 and the count to 8. This tells the sequence to begin at the first frame and animate consecutively through all frames until the end.

Following this, the optional time parameter defines the total duration of the sequence in milliseconds. The loopCount parameter defines how many times the sequence should loop repeat.

Depixelizing Pixel Art: Upscaling Retro 8-bit Games

Set this to any positive integer to loop the sequence that number of times. Alternatively, to loop the sequence indefinitely, set loopCount to 0. If looping is set, you can also include the loopDirection parameter.The algorithm identifies pixel-level details to accurately shade the new image — but more importantly, the algorithm can create smooth, curved contour lines from only-connected-on-the-diagonal single pixels.

Look at the Super Mario World dolphin below, and compare it to the original source sprite below that: the results speak for themselves. To achieve such beautiful images, the researchers use a complex blend of pixel analysis and spline curves.

VOXLINK Vs THOR HDMI to HDMI 4K UPSCALERS.

These approaches in specific, and vectorization of bitmaps in general, are nothing new — Adobe Illustrator does it quite well — but in this case, because the researchers were only working with 8-bit pixel art, they could create a very specialized algorithm.

Finally, these pixel cells groups are re-shaped, smoothed with spline curves, and then rendered as edges or shaded areas. For a better idea of just how accurate their algorithm is, you should look at the other nearly all Nintendo-related samples in the Depixelizing Pixel Art research paper.

Joined: Nov 11, Posts: I know this is a loaded topic, as I've looked into it before. It seems as though it's more effort than what it's worth.

Between all the different supported resolutions, how does one make pixel perfect art? I want to make pixel art. I've found assets that supposedly resolve this issue, but they don't always work? Joined: Dec 15, Posts: What game are you planning, I use sprites 64x64 on all resolutions and fiddle with the cameras orthographic projection size, mine is a game from mind you so I wanted that pixel feel.

But you can do pixel perfect, it just might be small on a higher resolution screen, that's why I fiddled with the camera size. Last edited: Dec 5, Here is my Camera code for you, I've left in a couple of other attempts see commented out code but this will give you an idea.
