WebThe OpenCV command for doing this is. 1. dst = cv2.resize(src, dsize[, fx[, fy[, interpolation]]]]) where fx and fy are scale factors along x and y, dsize refers to the output image size and the interpolation flag refers to which method we are going to use. Either you specify (fx, fy) or dsize, OpenCV calculates the other automatically. Webfx和fy分别表示水平和垂直方向的缩放比例，可以是一个浮点数或者整数。如果fx和fy都是1，则表示不进行缩放；如果fx和fy都小于1，则表示缩小图像；如果fx和fy都大于1，则表示放大图像。 总结 resize函数是CV2中用于调整图像大小的重要函数，可以帮助我们快速地 ...
