Keras implementation of Faster R-CNN: Towards Real-Time Object Detection with Region Proposal Networks. cloned from https://github.com/yhenon/keras-frcnn/

Please note that I currently am quite busy with other projects and unfortunately dont have a lot of time to spend on this maintaining this repository, but any contributions are welcome!

USAGE:

• Both theano and tensorflow backends are supported. However compile times are very high in theano, and tensorflow is highly recommended.

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

  The classes will be inferred from the file. To use the simple parser instead of the default pascal voc style parser, use the command line option -o simple. For example python train_frcnn.py -o simple -p my_data.txt.

• Running train_frcnn.py will write weights to disk to an hdf5 file, as well as all the setting of the training run to a pickle file. These settings can then be loaded by test_frcnn.py for any testing.

• test_frcnn.py can be used to perform inference, given pretrained weights and a config file. Specify a path to the folder containing images: python test_frcnn.py -p /path/to/test_data/

• Data augmentation can be applied by specifying --hf for horizontal flips, --vf for vertical flips and --rot for 90 degree rotations

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].
• The theano backend by default uses a 7x7 pooling region, instead of 14x14 as in the frcnn paper. This cuts down compiling time slightly.
• The tensorflow backend performs a resize on the pooling region, instead of max pooling. This is much more efficient and has little impact on results.

Example output:

ISSUES:

• If you get this error: ValueError: There is a negative shape in the graph!
  than update keras to the newest version

• This repo was developed using python2. python3 should work thanks to the contribution of a number of users.

• If you run out of memory, try reducing the number of ROIs that are processed simultaneously. Try passing a lower -n to train_frcnn.py. Alternatively, try reducing the image size from the default value of 600 (this setting is found in config.py.
