英語の技術説明
JPG, PNG, WebP, BMP, GIF (first frame) or AVIF; up to 30 MiB and 60 megapixels; output up to 16 megapixels (larger images are reduced). Masks are computed on a preview of up to 1,024 px and refined to full resolution with a guided filter, so fine hair, fur, glass, smoke and subjects coloured like their background need manual correction. The people model targets front-facing people; distant or very small subjects are approximate. The AI models download about 28 MB (people) or 18 MB (objects) once from this site; Solid colour and Box select need no model.
Four methods. Solid colour removes the edge colour or clicked colours by CIELAB distance, either connected to the borders and clicks or everywhere, with colour-fringe removal on semi-transparent edges. Box select runs GrabCut (Gaussian colour models and a Boykov–Kolmogorov minimum cut) in a local worker and recalculates with your Keep and Erase strokes. People uses the MediaPipe Selfie Multiclass model and Click object uses MediaPipe MagicTouch, both Apache 2.0, running with WebAssembly in the browser; several clicks select several objects. Edge tools: guided-filter refinement, speck removal, shrink or grow and softening. Export PNG or WebP with transparency, or JPG; crop to the subject with a margin; replace the background with a colour, a blurred copy of the photo or your own image; copy a PNG to the clipboard. Undo keeps the last 25 changes. Images are never uploaded.
Load the mug example: Box select separates the mug from the patterned background. Paint Erase over any leftover, choose a white background, crop to the subject and download a JPG for a product listing.
