Add color_match: colour-aware (HSV) template matching#394
Merged
Conversation
Every visual_match matcher grayscales first, so red vs green of identical shape is indistinguishable; color_region finds known-colour blobs but can't template-match a multi-colour glyph. Match on HSV hue/saturation with a colour-distance metric (TM_SQDIFF_NORMED, not correlation which normalises away the absolute hue). Reuses color_region's RGB loaders and visual_match's resize/NMS/Match.

摘要
新增
match_color/match_color_all— 在 HSV 色相/飽和度通道上做色彩感知樣板比對。visual_match每個比對器都先轉灰階,故形狀相同的紅色與綠色狀態指示燈對match_template無法區分;color_region找已知顏色的 blob 卻無法以外觀對多色字形做樣板比對。本功能以色彩距離度量(
TM_SQDIFF_NORMED,而非相關——相關會把絕對色相正規化掉,使紅→綠邊與黑→藍邊同分)在 H/S 通道比對,定位灰階比對會塌掉的色彩辨識目標。重用color_region的 RGB 載入器與visual_match的 resize/NMS/Match;haystack可注入。註:平坦純色 patch 無通道變異,純色 blob 請用find_color_region;本功能適用於有色彩結構的目標。Qt-free。五層
