Pytorch transfer learning error: The size of tensor a (16) must match the size of tensor b (128) at non-singleton dimension 2

Currently, I'm working on an image motion deblurring problem with PyTorch. I have two kinds of images: Blurry images (variable = blur_image) that are the input image and the sharp version of the same images (variable = shar_image), which should be…

Is there a method to copy the amount of motion blur of one image to another in python, preferably using opencv?

I'm adding an image in a video stream and would like to adjust the amount of motion blur so it matches the surroundings in the video stream. I would like to detect how much horizontal and vertical motion blur is present in a region of interest (ROI)…
