EDGE CHECK
SMART REFINE
Paint roughly over the wrong area.
Green keeps an area. Red removes it. PICORN grows your hint through the connected region, then rebuilds the soft alpha along the visible edge.
Edge matting ready
Paint directly on the result
Check the edge:Switch between black, white and pink. Paint green over anything that is missing. Mark unwanted leftovers in red.
A small model, plus image-aware correction.
One compact alpha model
A 524k-parameter ONNX graph predicts a soft foreground matte instead of a hard cutout.
Edges that follow the image
Eight small WebGPU passes follow similar colours. A guided pass cleans the alpha without erasing hair, wires or small holes.
Hints that understand regions
The refine brush builds a local trimap, grows through connected pixels and keeps changes inside a controlled band.
