Hi. I'm trying to use FlannMatcher with HierarchicalClusteringIndexParams and binary descriptors. It throws the following error:
OpenCV Error: Unsupported format or combination of formats (type=0 ) in cv::flann::buildIndex_, file D:\dev\opencv\source\modules\flann\src\minifla nn.cpp, line 315
It works fine with LshIndexParams.
Am I missing something?

EDIT: Solved. You have to convert Mat to float(CV_32F).

EDIT:
Solved. You have to convert descriptors to float(CV_32F).float(CV_32F) before adding them to the matcher.
Query descriptors also have to be converted to float.
