Add edge_match: edge-shape (Chamfer) template matching#380
Merged
Conversation
Intensity NCC drops when a control is re-filled or re-themed, and ORB needs corner texture flat-design glyphs lack. Match by edge shape instead: Canny both images, distance-transform the scene edges, slide the template's edges over it and score by mean edge-to-edge distance (Chamfer). A perfect outline aligns at ~0 cost regardless of fill. Reuses visual_match's loaders/resize/NMS/Match and edge_lines's Canny default.

摘要
新增
edge_match/edge_match_all/chamfer_distance— 以邊緣形狀(Chamfer / 距離轉換)定位模板。強度相關(visual_match)在同一控制項以不同填充 / 漸層 / 主題 / 抗鋸齒繪製時分數下降;ORB 特徵比對(feature_match)需要扁平設計圖示(漢堡選單、單純箭號)缺乏的角點紋理。本功能改以邊緣形狀比對:對兩圖跑 Canny,對場景邊緣建立距離轉換,把模板邊緣滑過它,以「每個模板邊緣到最近場景邊緣的平均距離」評分(Chamfer)。完美對齊的成本約為 0,與形狀如何填充 / 著色無關。重用
visual_match的灰階載入器 / resize / NMS /Match與edge_lines的 Canny 預設。haystack可注入;Qt-free。五層
utils/edge_match/—edge_match、edge_match_all、chamfer_distance。je_auto_control匯出 +__all__。AC_edge_match({found, match})/AC_edge_match_all({count, matches})。ac_edge_match/ac_edge_match_all(read-only)。測試
test/unit_test/headless/test_edge_match_batch.py— 不同灰階仍以輪廓找到形狀(score>=0.9、位置正確)、chamfer 距離近 0、空白→None、edge_match_all NMS 去重。6 passed。ruff / bandit / radon / float-scan / Qt-free 全乾淨。
