## Description

Anime4K is a collection of graphics shaders and image processing algorithms designed to enhance the visual quality of animated media. It functions as a real-time upscaling engine that increases the resolution of video content during playback, allowing for higher fidelity viewing without the need to permanently re-encode source files.

The project distinguishes itself by utilizing hardware-accelerated rendering to perform complex image reconstruction directly on the graphics card. By employing a pass-based pipeline, it chains multiple processing stages to refine frames iteratively, ensuring that visual enhancements are applied with low latency and high performance.

The core processing capabilities include specialized techniques for edge detection, convolution filtering, and luma-chroma separation. These methods work in tandem to sharpen lines, smooth textures, and remove noise or compression artifacts, specifically targeting the aesthetic requirements of hand-drawn animation. The implementation relies on a library of programmable shaders that manage video data through efficient buffer handling to maintain real-time output.
