7、Opencv库“resize()”函数调整图像的尺寸 当一张图像尺寸不合适时，我们可以通过Opencv库中的“resize()”函数对它进行缩放来调整图像的尺寸。ret, img = cap.read()#按帧读取图像if ret:'''crop the center of the frame and resize to (240, 320) while keeping image ratio. '''# 裁剪框架的中心...
w =int(w)ifh <= dst_h: image_dst = cv2.resize(image_src, (dst_w,int(h)))else: image_dst = cv2.resize(image_src, (int(w), dst_h)) h_, w_ = image_dst.shape[:2]returnimage_dst 我们使用img = self.resize_keep_aspectratio(image, [500, 500])即可进行调用,其中虽然传递为[50...

resized = cv2.resize(image, dim) cv2.imshow("Aspect Ratio Resize", resized) cv2.waitKey(0) 我们计算新宽度与旧宽度的比率(恰好是0.5)。 在此,我们指定新图像的尺寸dim 。我们知道,我们希望有一个300像素宽的图像,但我们必须乘以该比例计算新高度h。
You can see this in the newly created image from the above code:image_400.jpg. It looks a bit squished horizontally. If you want to resize images and keep their aspect ratios, then you should instead use thethumbnail()function to resize them. This also takes a two-integer tuple argument...
Finally, theresizeattribute reduces the size of the image keeping its ratio aspect using the key argumentswidthorheightlike in the snippet. It is possible to set a custom size explicitly using a tuple with the new dimensions(width, height). ...
OpenCV Resize Image - We learn the syntax of cv2.resize() and how to use this function to resize a given image. We can use cv2.resize() function to upscale, downscale, or resize to a desired size (considering or not considering the aspect ratio).
window size; (2) [DONE] option to resize images to fit current window size? (3) avoid scrolls if image size is less than window max size: use Label if imgwide <= scrwide and imghigh <= scrhigh? New in 1.1: updated to run in Python 3.1 and latest PIL; ...
