Description

Specify that Feature Detectors and Descriptor Extractors have to convert a given image to their type in case of CV_8UC3 image themselves and guarantee this by unit test. Otherwise we have to convert an image manually depending of the required type and it's not flexibly. I've added such inner conversion for some Detectors and Descriptors before, but there is not the test that guarantees that it's supported by all corresponding features2d algorithms.
