Progress

Image Classification
Instance Segmentation
Semantic Segmentation

lastest: I have released beta version Instance Segmentation code for COCO. Please refer to maskrcnn branch

Installation

torch==1.1.0
torchvision==0.2.0

Dataset

Download the ImageNet dataset and move validation images to labeled subfolders
- To do this, you can use the following script: https://raw.githubusercontent.com/soumith/imagenetloader.torch/master/valprep.sh

Instance Segmentation and Semantic Segmentation

Please directly put "Adaptive-anti-Aliasing/models_lpf/layers/pasa.py" this module before downsampling layers of the backbone except the first convolution layer. We adopt implemantation directly from:

Instance Segmentation: MaskRcnn

Semantic Segmentation: Deeplab V3+ and TDNet
