Caffe: Convolutional Architecture for Fast Feature Extraction

Created by Yangqing Jia, Department of EECS, University of California, Berkeley. Maintained by the Berkeley Vision and Learning Center (BVLC).

Caffe aims to provide computer vision scientists with a clean, modifiable implementation of state-of-the-art deep learning algorithms. Network structure is easily specified in separate config files, with no mess of hard-coded parameters in the code. Python and Matlab wrappers are provided.

At the same time, Caffe fits industry needs, with blazing fast C++/Cuda code for GPU computation. Caffe is currently the fastest GPU CNN implementation publicly available, and is able to process more than 20 million images per day on a single Tesla K20 machine *.

Caffe also provides seamless switching between CPU and GPU, which allows one to train models with fast GPUs and then deploy them on non-GPU clusters with one line of code: Caffe::set_mode(Caffe::CPU).

Even in CPU mode, computing predictions on an image takes only 20 ms when images are processed in batch mode.

Caffe is developed with the community by the Berkeley Vision and Learning Center. We welcome contributions!

To join in, please note this policy:

• Do your work in feature branches.
• Bring your work up-to-date by rebasing onto the latest dev. Polish your changes by interactive rebase if you like too.
• Pull request your contribution to BVLC/caffe's dev branch for discussion and review.
• dev is for new development, community contributions, and testing.
• master is handled by BVLC, which will integrate changes from dev.
