The codes are with the CVPR2016 paper ["CRAFT Objects from Images"](http://arxiv.org/abs/1604.03239).
The codes are with the CVPR2016 paper ["CRAFT Objects from Images"](http://byangderek.github.io/projects/craft.html).

In a word, we extend the conventional two-stage object detection framework (first locating object proposals, then classifying object categories) to a four-stage pipeline, in which the proposal localization task is solved with a cascade network of Region Proposal Network (RPN) and Fast R-CNN to improve the proposal quality, while the object classification task is handled by a cascade network of two Fast R-CNN nets with different objective functions (one-hot classification and one-vs-rest classification) to eliminate false positives.

We name our approach "CRAFT" (short for "Cascade Rpn And FasT-rcnn") and show considerable improvement over Fast R-CNN and Faster R-CNN baselines on PASCAL VOC 07/12 and ILSVRC datasets. For more details please refer to our [CVPR2016 paper](http://arxiv.org/abs/1604.03239).

The codes are built on [RPN](https://github.com/ShaoqingRen/faster_rcnn) (Stage 1) and [Fast R-CNN](https://github.com/rbgirshick/fast-rcnn) (Stage 2,3,4). It would be easier to use the codes if you are familiar with these two projects.

### Experimental results ###
### Results ###
| training data | test data | mAP
------------------------- |:--------------------------------------:|:--------------------:|:-----:
CRAFT, VGG-16 | VOC 2007 trainval + 2012 trainval | VOC 2007 test | 75.7%
CRAFT, VGG-16 | VOC 2012 trainval | VOC 2012 test | 71.3%

Note: The real mAP results may vary a little from the above results reported in the paper. We do not adopt joint training between RPN and Fast R-CNN currently.
