papadanku/CShade

Comprehensive HLSL shader library implementing temporal video processing (hierarchical Lucas-Kanade optical flow, motion stabilization, datamoshing) alongside conventional image filters (FidelityFX CAS/RCAS, FXAA, bilateral upsampling, local contrast normalization). Shaders support inter-shader merging with configurable RGBA channel output, temporal smoothing via hardware blending, and spot-metering for adaptive exposure. Includes reusable `.fxh` algorithm headers and UI markers denoting depth-buffer requirements, performance costs, and shader interdependencies.
