Caffe_train

Our modified caffe for training multi-person pose estimator. The original caffe version is in July 2016. This repository at least runs on Ubuntu 14.04, OpenCV 2.4.10, CUDA 7.5/8.0, and CUDNN 5.

The full project repo includes detailed training steps and the testing code in matlab, C++ and python.

We add customized caffe layer for data augmentation: cpm_data_transformer.cpp, including scale augmentation e.g., in the range of 0.7 to 1.3, rotation augmentation, e.g., in the range of -40 to 40 degrees, flip augmentation and image cropping. This augmentation strategy makes the method capable of dealing with a large range of scales and orientations. You can set the augmentation parameters in setLayers.py. Example data layer parameters in the training prototxt is:

layer {
  name: "data"
  type: "CPMData"
  top: "data"
  top: "label"
  data_param {
    source: "/home/zhecao/COCO_kpt/lmdb_trainVal"
    batch_size: 10
    backend: LMDB
  }
  cpm_transform_param {
    stride: 8
    max_rotate_degree: 40
    visualize: false
    crop_size_x: 368
    crop_size_y: 368
    scale_prob: 1
    scale_min: 0.5
    scale_max: 1.1
    target_dist: 0.6
    center_perterb_max: 40
    do_clahe: false
    num_parts: 56
    np_in_lmdb: 17
  }
}

Caffe

Caffe is a deep learning framework made with expression, speed, and modularity in mind. It is developed by the Berkeley Vision and Learning Center (BVLC) and community contributors.

Check out the project site for all the details like

• DIY Deep Learning for Vision with Caffe
• Tutorial Documentation
• BVLC reference models and the community model zoo
• Installation instructions

and step-by-step examples.

Please join the caffe-users group or gitter chat to ask questions and talk about methods and models. Framework development discussions and thorough bug reports are collected on Issues.

Happy brewing!
