技術アーキテクチャと実行の仕組み
Alpha Channel Euclidean Color Distance
The engine samples background border pixels, calculates Euclidean distance across RGB color space for each pixel matrix, and applies progressive alpha transparency interpolation to boundary pixels.
Distance = sqrt((R - R0)^2 + (G - G0)^2 + (B - B0)^2)技術的な制限と運用上の制約
- Works best when there is noticeable contrast between the foreground subject and background.
