Frame 0002 · Local Qwen boundary choices

0/4 choices exactly match the current reference.

Block 01 · DIFF

Reference: C2 (+128 px)
Local Qwen: C1 (+64 px) · confidence 0.90

Qwen reason: C1's white boundary with black halo best encloses the entire defocused parasol including its thin tips and translucent fringe without leaking outside the object's visible extent.

Reference reason

The white C1 line leaves a coherent cyan spoke/blur streak at or just outside its lower-right boundary; the magenta C2 line is the first candidate that clearly encloses it.

independent input A · true RGB
independent input B · biased residual

Block 02 · DIFF

Reference: C2 (+128 px)
Local Qwen: C1 (+64 px) · confidence 0.90

Qwen reason: C1's white/black halo boundary tightly follows the defocused parasol's visible edges, including thin tips and translucent fringe, without missing any coherent part.

Reference reason

A long lower-right residual streak and the matching defocused wooden tip remain outside C1, while C2 encloses both with a visible safety margin.

independent input B · biased residual

Block 03 · DIFF

Reference: C2 (+128 px)
Local Qwen: C1 (+64 px) · confidence 0.90

Qwen reason: C1's white/black halo most accurately traces the defocused parasol's visible edges, including thin tips and translucent fringe, without leaking into coherent residual outside its boundary.

Reference reason

C1 only narrowly meets the faint continuation and is not a safe boundary under the residual veto rule; C2 is the smallest candidate with unambiguous clearance.

Block 04 · DIFF

Reference: C2 (+128 px)
Local Qwen: C1 (+64 px) · confidence 0.90

Qwen reason: C1's white boundary with black halo most accurately traces the defocused parasol's visible edges, including thin ribs and translucent fringe, without including extraneous background pixels.

Reference reason

The diagonal parasol-related continuation approaches C1 too closely to certify full coverage; C2 is the first line that safely contains it despite adding some background.
