I convert mobilenet-0.25 mxnet model (trained by yangfly) to caffe model

I convert R50 mxnet model to caffe model BaiDuYun | Google Drive

• I have checked the output of the two models be the same.

• For same input images, the output of the two detector (python version and cpp version) is same.

(the code is too simple, only for reference 23333)

This is anchor parsing demo, NO INFERENCE, you should replace your own inference header and code (caffe/ncnn/feather .etc) in the source code

Update 2019.5.28

R50: Because of the GPU memory limited, I set max(width, height) to 1000 and test it on WiderFace_val set for SINGLE SCALE, NO MULTI-SCALE, NO FLIP, results as follows:

wider val	easy	medium	hard
python version	92.25	88.86	64.02
cpp version	91.36	87.15	62.22

Update 2019.5.27

mnet: I test on WiderFace_val set for SINGLE SCALE, NO MULTI-SCALE, NO FLIP, results as follows:

wider val	easy	medium	hard
python version	83.28	77.02	39.52
cpp version	83.04	76.84	39.43

You can see the two detect results as results/cpp_detect and results/python_detect. The main cause of the difference in test results is the numerical precision difference between C++ and python.

TODO

• implement bbox_vote
• multi-scale test
• speed benchmark (CPU/ARM)
• new models
