how to detect objects using the cnn?

[kingvision]

hi, liu
i had used your open cnn code for classifying objects. a few days ago, i started to think that how to detect objects using the cnn. can you give me some ideas or do you have plans to implement the detection issue using cnn?

thanks

You mean like https://github.com/rbgirshick/rcnn?

I have some ideas to implement this, but the naive implementation is too slow to be practical (I am looking for something at around 1s per frame at least).

Yes, i mean like this.

Would it be faster with https://github.com/rbgirshick/fast-rcnn ?
