Do the filters in deconvolution layer same as filters in convolution?
$begingroup$
I am trying to understand how the deconvolution works in Convolutional Neural Network for image segmentation problem. I have seen this definition:
Filters used in deconvolution is just the transpose of the convolution matrix.
Does this mean that the convolution layer and deconvolution layer shares the same filters? Do we train a separate set of filters for deconvolution layer?

Here, I think, you can find good visuals and explanations for convolution/deconvolution arithmetic.

Thank you for your prompt answer. I have looked through the material. It is very useful and clear but I still have a little confusion. It looks to me that 1. In convolution layer, we reshape our filters to form a matrix (w) so we can do matrix multiplication; 2. In deconvolution layer, we take the transpose of the matrix (w from convolution layer) and take that as the set of filters to use in deconvolution. Is this correct?

Here's a very nice intuitive explanation on why we use the same set of filters in both convolution and deconvolution layer.

No, these two layers do not share the same filter parameters. By coding and decoding you increase the representation power and enlarge the receptive fields.
