2015-07-15 11:33:06 -0600 | commented question | What is the distance used by K-nearest neighbour in opencv The implementation of k nearest neighbour in opencv was not professional! In addition, we can not get the indices of the k-nearest neighbours and we can note use an other distance. |
2015-07-15 11:26:20 -0600 | commented question | What is the distance used by K-nearest neighbour in opencv In fact I need to use the chi-2 square distance because I have implemented it on mathematica and it gives a good results in my case. I need to use it with opencv knearest neighbours. |
2015-07-15 11:12:51 -0600 | commented question | What is the distance used by K-nearest neighbour in opencv So, what is the solution to use other distances than euclidian distance? I think it was a bad idea to use just euclidian distance!! They have to make the distance used as an input parameters! |

2015-07-14 23:02:02 -0600 | asked a question | What is the distance used by K-nearest neighbour in opencv Hello, I am using the machine learning k-nearest neighbour algrithm c++. I have a dataset with a high dimensional features. So, the euclidian distance will be not the best. I try to find which distance used in knearest.cpp to change it and used different distances but I could not because the code lacks comments. I find this block in the 189 but It seems that it not used in the find_nearest function. Any help? |
