ChromaKey & Despill (chromakey)

The chromakey package isolates colored backdrops (green or blue screens) and suppresses green spill reflections on skin and clothing.

Quick Example

import "github.com/farshidrezaei/vidonex/chromakey"

options := chromakey.Options{
    KeyColor:   types.HexColor("#00FF00"),
    Similarity: 0.25, // Tolerance for color variation
    Smoothness: 0.10, // Edge feathering
    Despill:    true, // Remove green reflections from actor
}

// Injects colorkey and despill nodes into filtergraph DAG
outputPad, err := chromakey.ApplyChromaKey(graph, inputPad, options)
