🔬

Click-to-Select Paradigm

Click anywhere on the subject you want to keep. Each click is a seed point. The engine automatically grows the selection outward to the nearest edges.

🧠

Seeded Region Growing

From each seed point, the selection expands through pixels with similar colours in CIE L*a*b* space — naturally stopping at object boundaries.

Sobel Edge Detection

A Sobel gradient map identifies strong edges in the image. The growing algorithm slows and stops at these edges for a sharp, accurate outline.
