I've been implementing an adaptation of Viola-Jones' face detection algorithm. The technique relies upon placing a subframe of 24x24 pixels within an image, and subsequently placing rectangular fea...

Please explain to me, in few words, how the Viola-Jones face detection method works.

I have been experimenting with face detection in OpenCV (Open Source Computer Vision Library), and found that one could use Haar cascades to detect faces as there are several of them provided...

I'm using a trained opencv cascade classifier to detect hands in video frames, and would like to lower my false positive rate. Reading up on the net, I saw you can do so by accessing the rejectLev...

Wanted to ask if there was any kind of face detection scheme suitable for video that would require minimal training time ideally about a few days rather than weeks like the Viola-Jones. I hav...

I'm trying to understand Viola Jones method, and I've mostly got it. It uses simple Haar like features boosted into strong classifiers and organized into layers /cascade in order to accomplish be...

I'm trying to implement P. Viola and M. Jones detection framework in C++ (at the beginning, simply sequence classifier - not cascaded version). I think I have designed all required class and module...
