You should not load the flann-file into a Mat (), as it is the place where the index is stored. It is a temporary object destroyed after the constructor was called. That's why the index isn't pointing anywhere useful when you call knnSearch (). Reading FLANN index error: the saved data size ( 100, 64) or type ( 5) is different from ...

WebApr 7, 2015 · 4. I have two set of points (cv::Point2f): setA and setB. For each point in setA, I want to find its nearest neighbor in setB. So, I have tried two methods: Linear search: for each point in setA, just simply scan through all points in setB to find nearest one. Using opencv kd-tree: _ First I built a kd-tree for setB using opencv flann:
WebDescription. example. Idx = knnsearch (X,Y) finds the nearest neighbor in X for each query point in Y and returns the indices of the nearest neighbors in Idx, a column vector. Idx has the same number of rows as Y. Idx = knnsearch (X,Y,Name,Value) returns Idx with additional options specified using one or more name-value pair arguments. granitemakeover.comhttp://duoduokou.com/cplusplus/64085792635234078246.html granite look porcelain tileWebenum flann_log_level_t log_level; /* determines the verbosity of each flann function */ long random_seed; /* random seed to use */ The algorithm and centers init fields can tak e the following v alues: chinnor bus timetableWebCreate a flann index using Kmeans.
