13 Nov 2013 Kernel Density Estimator Reliable and extremely fast kernel density estimator for one-dimensional data Author: Zdravko Botev

Dear Botev,

I have encountered a problem with your implementation and seeking your help. The PDFs obtained using translated versions of the signal (image histogram, in this case) is not the same.

data = [23 23 23 22 22 22 21 22 23];
data = [53 53 53 52 52 52 51 52 53];
MIN = 0
MAX = 255
n = 256;

[bandwidth,density,xmesh,cdf]=kde(data,256,MIN,MAX)

This gives a good uni-modal estimate, whereas the second one is incomprehensible.

[bandwidth,density,xmesh,cdf]=kde(data2,256,MIN,MAX)

Please take a look at the density plots in each case.

This might be a problem with the bandwidth estimation but I don't know how to solve it.

Any help is appreciated.

Hello David,

Do you know how to find the image point corresponding a point in the log-polar transformed space? Is there an easy way to do it?
