2016-04-24 02:04:01 -0600	asked a question	Is it safe converting to a Mat itself with different type? The following code can be compiled without error. However, is it safe doing this? `Mat im = imread('test.jpg', CV_LOAD_IMAGE_GRAYSCALE); im.convertTo(im, CV_32F1);`

2015-12-18 08:52:17 -0600	asked a question	What's the difference between `KDTreeIndex` and `KDTreeSingleIndex`? In their comments, both says: `/** * Randomized kd-tree index * * Contains the k-d trees and other information for indexing a set of points * for nearest-neighbor matching. */` Anyone can tell me the exact difference of the two Index classes?
