+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed

+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+# keras-frcnn
+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.

+![ex4](http://i.imgur.com/i5UAgLb.png)
+
+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`.
