1. 函数 用OpenCV 标注 bounding box 主要用到下面两个工具——cv2.rectangle() 和 cv2.putText()。用法如下 # cv2.rectangle() # 输入参数分别为图像、左上角坐标、右下角坐标、颜色数组、粗细 cv2.rectangle(img, (x,y), (x+w,y+h), (B,G,R), Thickness) # cv2.putText() # 输入参数为图像...

Is there a simple way, using OpenCV, to crop the "after script" image so that it includes only the four-sided bounding boxes? Sample output: EDIT: I'm currently working on a solution that finds the first/last all-black pixel line going vertically/horizontally. It'll work, but was wonde...
