# Foreground Object Removal Feature
|
|
|
|
## Description
|
|
Remove foreground objects via tap detection with smart brush fallback.
|
|
|
|
## Acceptance Criteria
|
|
- [ ] User taps object in photo with Object tool selected
|
|
- [ ] `VNGenerateForegroundInstanceMaskRequest` attempts to isolate object
|
|
- [ ] If mask found: preview shown, user confirms, inpaint executes
|
|
- [ ] If no mask found: "Use brush to select" prompt displayed
|
|
- [ ] Smart brush fallback:
|
|
- User paints rough selection over object
|
|
- App refines selection to nearest strong edges
|
|
- Edge refinement uses gradient magnitude analysis
|
|
- Refined mask preview shown
|
|
- User confirms refined mask
|
|
- [ ] Brush tool settings: size slider (1-100px)
|
|
- [ ] Edge refinement toggle available
|
|
- [ ] Clear messaging about limitations:
|
|
- "Works best on objects that stand out from background"
|
|
- "Low-contrast objects may require manual selection"
|
|
- [ ] Performance: detection < 500ms, edge refinement < 200ms
|
|
|
|
## Technical Notes
|
|
- Vision detects visually distinct foreground regions
|
|
- It separates by contrast, not semantic understanding
|
|
- Edge refinement: compute gradient magnitude, snap brush stroke to nearby edges
|
|
- `EdgeRefinement.swift` utility for gradient-based snapping
|
|
|
|
## Edge Cases
|
|
- Object blends with background: Vision returns no mask, prompt brush
|
|
- Very large object: may affect inpaint quality, warn if >30% of image
|
|
- Object at image edge: handle boundary in mask and inpaint
|
|
- User brush stroke misses object: edge refinement helps, but may need retry
