Thx for ur help.I read the article and got a rough understanding of the artifact causes.
But still confused. And I’d like to know the specific modification.
e.g, Now I use 3 deconv with k=4,s=2(I got the k=2s from this article https://stackoverflow.com/questions/49554650/noise-in-image-segmentation-result 33),which said k set to 2s should be a solution.I did this modification but got no obvious elevation.
My architecture is : deconv1,deconv2, deconv3, then conv, three deconv all set to k=4, s=2 to enlarge twice as their input.the final conv is a k=1,s=1 conv layer to convert feature to channel-wise class to do the segmentation work.
