2012-09-20 01:42:32 -0600	asked a question	BRISK runs out of memory on iOS Hi, i tested the newly introduced BRISK detector/extractor https://github.com/Itseez/opencv/blob/master/modules/features2d/src/brisk.cpp When i run BRISK on a little demo app keypoints are detected and extracted, but also memory warnings pop up. I've done some profiling and it seems the kernel generation (https://github.com/Itseez/opencv/blob/master/modules/features2d/src/brisk.cpp#L230) consumes a lot of memory and causes the issues. Has anyone else spotted the same behavior (especially on mobile devices)? bernhard

2012-08-18 12:17:50 -0600	asked a question	Adding a new Detector/Descriptor to Evaluation-Sample Hi, yesterday i evaluated a few feature detectors and descriptors. I used the detector_descriptor_evaluation.cpp, which is located in the samples folder of the main repo. After a few modifications the tests worked as expected. Unfortunately the list of the detectors and descriptors is out-of-date (e.g. ORB or FREAK are not included). I added ORB myself and it seems to work...but there is one little problem. All other detectors and descriptors have an xml file with quality results, e.g. SURF_res.xml (located in opencv_extra/testdata/cv/detectors_descriptors_evaluation/detectors) So my question is: For what exactly is this file good for and how can i generate one for the detectors which are not included?
