您好,我最近在研读你的ctpn项目代码,有一个小小的疑问,为什么所有anchor的bottom坐标都比 top坐标要大?比如./lib/generate_gt_anchor.py 第37行, h = y_bottom[i] - y_top[i] + 1 # the height of anchor box 高度的计算默认bottom比top大,下面的cal_y_top_and_bottom()函数中,y_top明显是从下往上找到的,而y_bottom是从上往下找到的。 相同的情况在./lib/tag_anchor.py文件的cal_y()函数中也出现了。 我对cv领域不太了解,想请问一下这个是后面训练有要求还是cv领域特有的讲究?
./lib/generate_gt_anchor.py
h = y_bottom[i] - y_top[i] + 1 # the height of anchor box

在ctpn/infer.py中
b1 = line[6] - line[7] / 2 # 根据高度和文本行中心线,求取文本行上下两条线的b值 b2 = line[6] + line[7] / 2 x1 = line[0] y1 = line[5] * line[0] + b1 # 左上 x2 = line[2] y2 = line[5] * line[2] + b1 # 右上 x3 = line[0] y3 = line[5] * line[0] + b2 # 左下 x4 = line[2] y4 = line[5] * line[2] + b2 # 右下
按理说,b1小于b2吧,y1应该是左下,y2是右下,y3是左上,y4是右上才对
Sorry, something went wrong.
