Is there some other method exect grid_sample() in python to apply the warp on sorce image using flow image?
Hi I have source image of 3D of shape (1, 256, 256). I have created the flow matrix with my desired translation, rotation and scaling of 3D with the shape of (2, 256, 256).
When I am applying grid_sample() from torch library it throw destination output of zeros element warp matrix.
Is there any other method in python or some other library to go with these to source and flow matrix.
I have tried OpenCV also but the output is not expected.
Please help me out. Thanks
