How to understand the line-nms?

lhao0301 opened this issue · comments

I find that the line-nms delete some boxes. It seems a little confusing. The left-top and right-top point are used as left-top and right-bottom point , respectively. The x-coordinate of left-bottom point is used as confidence. It is a little difficult to understand it.

keep_inds=nms(text_lines, TextLineCfg.TEXT_LINE_NMS_THRESH)
