Pytorch code for paper "Image Compressed Sensing Using Non-local Neural Network" TMM 2021.

Overview

NL-CSNet-Pytorch

Pytorch code for paper "Image Compressed Sensing Using Non-local Neural Network" TMM 2021.

Note: this repo only shows the strategy of plugging the Non-local module (with non-local coupling loss constraint) into a simple CNN-based CS network (in the measurement domain and feature domain). For more details of the NL-CSNet atchitecture, please refer to the paper.

Framework

Requirements and Dependencies

  • Ubuntu 16.04 CUDA 10.0
  • Python3 (Testing in Python3.5)
  • Pytorch 1.1.0
  • Torchvision 0.2.2

How to Run

Training NL-CSNet

  • Preparing the dataset for training

  • Editing the path of training data in file train.py.

  • For NL-CSNet training in terms of subrate=0.1:

python train.py --sub_rate=0.1 --block_size=32

Testing NL-CSNet

  • Preparing the dataset for testing

  • Editing the path of trained model in file test.py.

  • For NL-CSNet testing in terms of subrate=0.1:

python test.py --cuda --sub_rate=0.1 --block_size=32

[TOG 2021] PyTorch implementation for the paper: SofGAN: A Portrait Image Generator with Dynamic Styling.

This repository contains the official PyTorch implementation for the paper: SofGAN: A Portrait Image Generator with Dynamic Styling. We propose a SofGAN image generator to decouple the latent space of portraits into two subspaces: a geometry space and a texture space. Experiments on SofGAN show that our system can generate high quality portrait images with independently controllable geometry and texture attributes.

    模型训练/测试时的显存开销问题。

    作者你好,非常感谢你的代码。我在训练和测试模型时发现显存的开销非常大,当crop_size设为128时,在3090(24GB显存)上batch_size最高仅能设为2。因此在这种情况下,测试时也会超出显存,即使降低feature的通道数(nl_feas)也依然存在显存开销巨大的问题。我看到您在文章中是用1080Ti跑的实验,想请教一下我的设定是否存在问题?您训练或测试时通常的显存开销是多大?谢谢!
