This class has only one method for the moment: resize. 简单来说就是调整PILImage对象的尺寸，注意不能是用io.imread或者cv2.imread读取的图片，这两种方法得到的是ndarray。, 而一般输入深度网络的特征图长宽是相等的，就不能采取等比例缩放的方式了，需要同时指定长宽：, 例如transforms.Resize([224, 224])就能将输入图片转化成224×224的输入特征图。, 这样虽然会改变图片的长宽比，但是本身并没有发生裁切，仍可以通过resize方法返回原来的形状：, 需要注意的一点是PILImage对象size属性返回的是w, h，而resize的参数顺序是h, w。, 大家一起学编程（python）: The CNN model takes an image tensor of size (112x112) as input and gives (1x512) size tensor as output. Using Opencv function cv2.resize () or using Transform.resize in pytorch to resize the input to (112x112) gives different outputs. 感谢博主的分享！, 大家一起学编程（python）: Did China shut down a port for one COVID-19 case and did this closure have a bigger impact than the blocking of the Suez canal? This video will show you how to use the Torchvision CenterCrop transform to do a rectangular crop of a PIL image. Resize ([256, 192]) res_pil_image = resize (pil_image) we can then use T.ToTensor this will actually scale by 255 and transform to tensor, it is equivalent to … PyTorch Faster/Mask RCNN resize images badly. MapTransform (keys, allow_missing_keys = False) [source] ¶.
