Keras implementation of Faster R-CNN: Towards Real-Time Object Detection with Region Proposal Networks

CURRENT STATUS:

• only resnet50 architecture is currently supported
• weights for theano backend coming shortly

USAGE:

• train_frcnn.py can be used to train a model. To train on Pascal VOC data, simply do: python train_frcnn.py /path/to/pascalvoc/

• the Pascal VOC data set (images and annotations for bounding boxes around the classified objects) can be obtained from: http://host.robots.ox.ac.uk/pascal/VOC/voc2012/VOCtrainval_11-May-2012.tar

• simple_parser.py provides an alternative way to input data, using a text file. Simply provide a text file, with each line containing:

filepath,x1,y1,x2,y2,class_name

For example:

/data/imgs/img_001.jpg,837,346,981,456,cow /data/imgs/img_002.jpg,215,312,279,391,cat

• test_frcnn.py can be used to perform inference, given pretrained weights. Specify a path to the folder containing images: python test_frcnn.py /path/to/imgs/

NOTES: config.py contains all settings for the train or test run. The default settings match those in the original Faster-RCNN paper. The anchor box sizes are [128, 256, 512] and the ratios are [1:1, 1:2, 2:1].
