Progressive Multi-Granularity Training

Code release for Fine-Grained Visual Classiﬁcation via Progressive Multi-Granularity Training of Jigsaw Patches (ECCV2020)

Requirement

python 3.6

PyTorch >= 1.3.1

torchvision >= 0.4.2

Training

Download datatsets for FGVC (e.g. CUB-200-2011, Standford Cars, FGVC-Aircraft, etc) and organize the structure as follows:
