Width (stitches)

Brightness

Contrast

Auto Enhance Contrast

Applies histogram equalization to improve tonal range of washed-out images before processing.

Anti-Confetti (Smoothing)

Removes stray single stitches. 0 is off, 1-3 increases edge-preserving smoothing.

Edge-Preserving Smooth

Smooths noise while keeping sharp color boundaries intact (0 = off, 1-5 = intensity).

Block Painting (Kuwahara)

Simplifies shapes into flat painterly blocks while keeping edges sharp (0 = off, 1-5 = intensity).

Morphological Cleanup

Refines shape boundaries using mathematical morphology. Open removes noise; Close fills holes.
