Why do the generators on my CycleGAN give the same output as input on custom dataset?
So I followed the tutorial code for image to image translation using cyclegan from here. I am training it on a custom dataset on Keras. What reason could there be for the network to not learn a translation? Both generators in the cyclegan give out…

How to deal with severe overfitting in a UNet Encoder/Decoder CNN in a task very similar to image translation?
I am trying to fit a UNet CNN to a task very similar to image to image translation. The input to the network is a binary matrix of size (64,256) and the output is of size (64,32). The columns represent a status of a communication channel where each…

In the U-Net architecture, h and w don't match, I don't know whether I misunderstood it or not
I'm confused about the image-transformation structure in a paper that I read. The output dimensions of the layers they concatenate do not match.
Should it actually be layer 9 and layer 7?
class ImageTransformationNetwork(nn.Module):

Can Encoder-Decoder network be used for different input and output?
Working on image translation problem. Got many pairs of input-output images, say sketch as input, translated sketch as output. Images are b&w with 1 pixel width sketch lines.
Can simple encoder-decoder be used to LEARN the image translation?
Code…

How can I rotate an image using only affine2d and transformPointsForward in Matlab?
I would like to rotate (30 degrees) an image in Matlab but without using imwarp, imtranslate, imrotate, imresize.
My code is following:
image = imread('image.jpg');
theta = 30;
tform = affine2d([cosd(theta) sind(theta) 0; -sind(theta) cosd(theta) 0;…

How to apply a rotation matrix R(3*3) and vector translation T(3*1) to an image in matlab?
I have two images I1 and I2, and I get the rotation matrix R (3*3) and the translation vector T (3*1) between this two images. Now I want to apply this R and T in I1 to get the aligned image J from I1. I try this code but didn't work :
J=(I1.*R)+T;…

how does cv2.warpPerspective works?
I did image registration between two images (img_source, img_ref) using the following code.
# Find homography
h, mask = cv2.findHomography(points1, points2, cv2.RANSAC)
# Use homography
height, width, channels = im2.shape
im1Reg =…
