10 May 2010 K Nearest Neighbors Program to find the k - nearest neighbors (kNN) within a set of points. Author: Ani Samosir, Ridha

i need code for r-nearest neightbour using sliding window concept start form window 3x3 then shift until window size of image reached. All of point is grouped based on color similarity using euclidian distance. Parameter for this code is count of r-nearest neightbour ( 25 ) and minimum color distance ( 6 ). Minimum color distance is a treshold for check the similarity between the point. So all of data point which have similarity distance color < 6 is taken for make a group. Start from window 3x3, define inisialization point X then memorizaed all data point ( 25 ) which color distance < 6.

The square distance is calculated (without square root) . Take a look a this tutorial:

really nice, simple and easy - but don't you need to take the square root for distances?

Is it fast for large dataset? Is it implemented using KD-tree?

can you tell me what is sortpos() and sortval()
