Thank you for you answer Josh, these red dots are actually an array, where each cell has a coordinate x and y. To be honest I wanted to export this red dots with the following structure: 590600,00 6890408,00 1019,04 This image I'm using each pixel has a geographic coordinate. But, at the moment I use the image in the scrip, the coordinates are lost and remains only basic pixel coordinates (i. e. 40, 412, 210). I'm quite new at scikit and python. So I'm trying to learn things with practice. Thanks for your attention Em quinta-feira, 9 de abril de 2015 17:22:51 UTC+2, Josh Warner escreveu:

@FARS - My recommendation was going to be applying some blur first, I'm glad that worked for you.

How have you labeled the red points in the image above? If they are in a separate - possibly boolean - array, you can extract the coordinate indices directly via `np.where` or `np.nonzero`. If not, we'll need a little more information about those red dots to advise.

Stefan,

Thanks for your help, but I end up solving the problem. I combined the gaussin filter plus the max filter. The result now is much better.

Now I'm strugling to export the local maxima points. Is there a function to export the points from the local maxima?

Cheers,

JP
