It can be run only with GPU because roi_pooling_2d layer has only GPU implementation.\n\n## Requirements\n\n- [OpenCV 3.0 with python bindings](http://opencv.org)\n- [Chainer 1.4](https://github.com/pfn/chainer)\n- [fast-rcnn](https://github.com/rbgirshick/fast-rcnn)\n- [dlib v18.18](https://github.com/davisking/dlib)\n\n## Create symlink\n\nCreate a symlink from the location of original [fast-rcnn](https://github.com/rbgirshick/fast-rcnn) dir to this project's root dir. (The below line assumes a environment variable `$FRCN_ROOT` has a path to the `fast-rcnn` source dir.)\n\n```\n$ ln -s $FRCN_ROOT ./\n```\n\nMake sure that all steps written in the `Installation (sufficient for the demo)` section of `README.md` in [fast-rcnn](https://github.com/rbgirshick/fast-rcnn) have been performed.\n\n## Convert model\n\nConvert caffemodel to chainermodel.\n\n```\n$ python scripts/load_net.py\n```\n\n## Test\n\nFirst you should prepare a sample image, and then\n\n```\n$ python scripts/forward.py --img_fn sample.jpg --out_fn result.jpg\n```\n\n### Result\n\n![](https://raw.githubusercontent.com/wiki/mitmul/chainer-fast-rcnn/images/result.jpg)\n'Overstekend wild' St. Janskerkhof Den Bosch \u0026copy; FaceMePLS (https://www.flickr.com/photos/faceme/5891724192)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmitmul%2Fchainer-fast-rcnn","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmitmul%2Fchainer-fast-rcnn","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmitmul%2Fchainer-fast-rcnn/lists"}
