High-Dimensional-LBP

My implementation of high dimensional lbp feature for face recognition based on

Dong Chen, Xudong Cao, Fang Wen, Jian Sun. Blessing of Dimensionality: High-dimensional Feature and Its Efficient Compression for Face Verification. Computer Vision and Pattern Recognition (CVPR), 2013.

I use openCV for face detection and IntraFace for facial landmark detection.

Details of the implementations can be found in

Bor-Chun Chen, Chu-Song Chen, Winston H. Hsu. Review and Implementation of High-Dimensional Local Binary Patterns and Its Application to Face Recognition, Technical Report TR-IIS-14-003, Institute of Information Science, Academia Sinica, 2014. (PDF)

If you use this code for your research, please kindly cite the technical report above.

##Prerequisites

###openCV

Install openCV and change the first line in src/Makefile to opencv home directory:

OPENCV_HOME = /path/to/opencv/

###IntraFace

Download IntraFace Library from http://www.humansensing.cs.cmu.edu/intraface/ (I used v1.0)

and put

1. libintraface.a to lib/
2. DetectionModel-v1.5.yml,TrackingModel-v1.10.yml to data/
3. **FaceAlignment.h **, Marcos.h, XXDescriptor.h to include/

##Build

change to src directory and type make

##Usage

If everythings goes right, there will be to binary files in bin/

face-detection will detect the largest face in the input images and crop the faces into a new image.

Usage: face-detection [-m model_file -o output_dir -s output_scale -l min_size] input_images

model_file: face detection model file, default: ../data/fdetector_model.dat
output_dir: output directory for face images, default: ./
output_scale: output face image size, default: 250
min_size: minimal face size for detection, default: 100
input_images: images for face detection

After face detection, we can extract the high dimensional LBP features using extract-lbp:

Usage: extract-lbp [-m model_dir -o output_dir] input_images

model_dir: model directory for landmark detection, default: ../data/
output_dir: output directory for lbp features, default: ./
input_images: face images for featrue extraction

The output will be image_name.lbp which contains 75,520 dimensional lbp features
