A Pytorch and TF implementation of the paper "Fast Dense Feature Extraction with CNNs with Pooling Layers"
Hello,
Would it be possible if you can give an example where the original network is an architecture like Resnet? This would be extremely helpful.
Thanks!
Hi,
I have a concern about the equality of the proposed method and the commonly used one. For example, if the image size is 240 * 240 and the patch size is 24 * 24, the receptive field of the commonly used method (i.e., extract all patches one by one from the whole image) would not exceed the patch size due to the fact that all patches are fed into the network independently for feature extraction. However, the receptive field of this FDFE seems to consider the region larger than 24 * 24 if the pooling operation is used.
Could you please explain why they are equal if we require the latent code (the results from feature extraction) is only generated from each fixed patch size (e.g., 24 * 24)?
Thanks,
Xiaohong
How could it be used? Thanks
the SlimNet has a 3-dimensions output with shape (-1, imH, imW) now.
but if we have a batch of images for input, should the net have output with 4-dimensions ? like(batch_size, -1, imH, imW)?
thanks.
Hi,
First, this is a great work that largely improves the processing speed for patch-based CNN. After reading the paper, I found the transpose-reshape operation might be replaced by the pixel shuffle that is provided by the PyTorch framework. Is it correct?
I'm looking forward to your reply.
Best,
Xiaohong
