Description

Description

I have tried the sample of Features2D + Homography to find a known object in the opencv_tutorial.pdf for android development.

I used FREAK extractor and BFMatcher(NORM_HAMMING), but it fails on this line:

matcher.match(descriptorsA, descriptorsB, matches);

And also I have tried other extractors and other matchers, the situation still not change at all:

OpenCV reports:

OpenCV Error: Assertion failed (type src2.type() && src1.cols src2.cols &&
(type CV_32F || type CV_8U)) in unknown function, file OpenCV\modules\core\src\stat.cpp, line 1803

If it is reproducible on 2.4.3.1 then current 2.4 can not be Ok. 2.4.3.1 is only 2 commits past 2.4 right now.
