ECCV2020: Adaptive Mixture Regression Network with Local Counting Map for Crowd Counting

Introduction

In this work, we introduce a new learning target named local counting map, and show its feasibility and advantages in local counting regression. Meanwhile, we propose an adaptive mixture regression framework in a coarse-to-fine manner. It reports marked improvements in counting accuracy and the stability of the training phase, and achieves the start-of-the-art performances on several author- itative datasets. For more details, please refer to our arXiv paper.

Framework

Demo

Getting Started

Prerequisites
- Python >= 3.5
- Pytorch >= 1.0.1
- other libs in requirements.txt, run pip install -r requirements.txt.
Data Preparation
- Download ShanghaiTech, UCF-QNRF, UCF_CC_50 datasets from the official websites and unzip them in ./ProcessedData.
- Run cd ./datasets/XXX/ and python prepare_XXX_mod64.py to resize images and generate training labels.
- UCF-QNRF: [home link], ShanghaiTech: [home link], UCF-CC-50: [home link]
Pretrained Model (Only for Training)
- Some Counting Networks (such as VGG, CSRNet and so on) adopt the pre-trained models on ImageNet. Download vgg16-397923af.pth from torchvision.models.
- Place the pre-trained model to ./models/Pretrain_model/.
- vgg16-397923af.pth : download link
