34 - opencv_createsamples is used to prepare a training dataset of positive and test samples.
35 opencv_createsamples produces dataset of positive samples in a format that is supported by
50 For training we need a set of samples. There are two types of samples: negative and positive.
52 detected objects. Set of negative samples must be prepared manually, whereas set of positive samples
85 Please note that you need a large dataset of positive samples before you give it to the mentioned
87 positive sample for absolutely rigid object like an OpenCV logo, but you definetely need hundreds
88 and even thousands of positive samples for faces. In the case of faces you should consider all the
