Add text_blocks: paragraph & list grouping of OCR lines#387
Merged
Conversation
text_regions merges glyphs into lines but nothing grouped those lines into paragraphs or detected lists; ocr/structure stops at flat rows. group_paragraphs starts a new paragraph wherever the vertical gap exceeds line_gap_factor x the median line height; detect_lists recognises bullet / ordinal items by their leading marker and left indent.

摘要
新增
group_paragraphs/detect_lists— 把 OCR 行分組成段落並偵測項目符號 / 編號清單。text_regions.find_text_lines把字形併成行,但沒有功能把那些行分組成段落或偵測清單;ocr/structure止於平面列。group_paragraphs在垂直間距超過line_gap_factor× 中位行高處開始新段落(標準留白分組啟發法);detect_lists以前導標記(•/-/*或1./2)/a.)與左縮排辨識清單項目,回傳{text, marker, indent, box}。純標準函式庫,作用於純行字典;重用table_grid_fill的框邊界讀取器。Qt-free。五層
