Higher-order Integration of Hierarchical Convolutional Activations for Fine-grained Visual Categorization

The implementation of “Higher-order Integration of Hierarchical Convolutional Activations for Fine-grained Visual Categorization” by Sijia Cai, Wangmeng Zuo and Lei Zhang.

Environment

• Ubuntu 14.04
• NVIDIA GeForce GTX TITAN X
• MatConvNet (v1.0-beta20)

Usage

• First you need to download the FGVC datasets (CUB, Aircraft and Cars) and unzip them into the folder “./datasets”
• Download the pretrained VGG16 model and put it into the folder “./models/pretrained_models”
• Compile MatConvNet with GPU and the cuDNN support
• Train: run hihca_main.m by setting runPhase=train
• Test: run hihca_main.m by setting runPhase=test
