mmocr.utils.stitch_boxes_into_lines(boxes, max_x_dist=10, min_y_overlap_ratio=0.8)

Note: part of its logic is inspired by @Johndirr (https://github.com/faustomorales/keras-ocr/issues/22)

Parameters

• boxes (list) – List of ocr results to be stitched

• max_x_dist (int) – The maximum horizontal distance between the closest edges of neighboring boxes in the same line

• min_y_overlap_ratio (float) – The minimum vertical overlapping ratio allowed for any pairs of neighboring boxes in the same line

Returns

List of merged boxes and texts

Return type

merged_boxes(list[dict])
