Face detection methods have traditionally trained on heterogeneous, even proprietary, datasets. As with most of the literature, we will use three databases: (1) positive training crops, (2) nonface scenes to mine for negative training data, and (3) test scenes with ground truth face locations.

Oct 06, 2016· With the results of the first mining session a lbp cascade classifier was trained to be used in stage 2. OpenCV has a built in cascade trainer via the opencv_traincascade command. The classifier used in this update is a 15 stage classifier trained with 1000 positive and negative images.
In this paper, we adopt the idea of cascade classifier in imbalanced web mining for fast classification, and propose a new asymmetric cascade learning method called FloatCascade to improve the accuracy.

Hi, In the OpenCV documentation I have come across the following statement, about loading cascade with GPU classifier: "Only the old haar classifier (trained by the haar training application) and NVIDIA's nvbin are supported for HAAR and only new type of OpenCV XML cascade supported for LBP."
My first guess is that data of classifier one is not used as negative training data for classifier two. It will make it more difficult to converge to a stable model, but it will force the model to look for features that are not similar between both cases.
