# SpriteDX - Introducing Anti-Corruption Model V1

We are introducing custom-trained Image-to-Image model for pixel art restoration called Anti-Corruption (AC) Model. I hear you. The name is menacing. It sounds like super intelligent AI trying to pluck out corrupt politicians. No, it’s not. It’s just Anti-pixel-art-Corruption Model. We named the process of converting real pixel arts into pseudo pixel art “corruption.“ And this “anti-corruption” model just does the opposite.

From blurry pseudo pixel art animation (corrupted):

To clean pixel art animations with transparency (anti-corrupted):

## What Does It Do?

**1\. Artifact Correction**: SpriteDX generates what we call “pseudo pixel art“ animations. The animation frames are often upscaled 4-5x with blurry edges. And simply using nearest neighbors leads to poor quality animations which are blurry.

**2\. Background Matting**: Because the video generation models output RGB frames, we do not have any transparent alpha channel. This model recovers the transparent alpha looking at the image.

## What’s Next?

Okay, the architecture is super simple and we have [whole slew of ideas](https://blog.sprited.app/spritedx-pixel-alignment-lab-note-3) to make it better (especially around sub-pixel animations), but it works and @[Pixel](@pixelthismarketing) says I should integrate this model ASAP instead of working on improvements. Let’s work on this today, and perhaps I can post Reddit post with this “update.”

First off we are replacing the template image’s background color from white to magenta:

Uploaded the model to Hugging Face:

Then, we write up a Custom node for this anti-corruption model:

Then updated the worker-comfyui to include this custom node:

Then updated the Stage 2 to do anti-corruption as part of its steps.

Then tested locally that the Stage 2 generates correct `clean_animation.webp` file:

Appears to be the case! 😀

One thing I notice is that when using magenta bg, the colors of characters get extra bright too. So this may be something we should note down and fix.

Resulting `clean_animation.webp`:

Gotta go pick up my kid. Next step is to change Stage 3 and Stage 4. Basically though, I can get rid of Stage 4 and make Stage 3 use the `clean_animation.webp` instead of `animation.webp`.
