我的问题是我需要在图像中的感兴趣区域周围绘制一个矩形.这怎么能在python中完成?我正在进行对象检测,并想在我认为在图像中找到的对象周围绘制一个矩形.
My issue is I need to draw a rectangle around regions of interest in an image. How can this be done in python? I'm doing object detection and would like to draw a rectangle around the objects I believe I've found in the image.
推荐答案
请不要尝试使用旧的 cv 模块,使用 cv2:
please don't try with the old cv module, use cv2:
import cv2 cv2.rectangle(img, (x1, y1), (x2, y2), (255,0,0), 2) x1,y1 ------ | | | | | | --------x2,y2
以附加以下后续问题:
cv2.imwrite("my.png",img) cv2.imshow("lalala", img) k = cv2.waitKey(0) # 0==wait forever
