How fo find the peaks using this function

Hello,

I'm trying to get lines from a 2D point cloud. Instead of displaying the points and use that figure as an image, I wanted to work on the points directly. I tried using this user function: Hough Transform for Point Clouds & Images, Hough Transform Matrix.

However I can't use the houghpeaks function because the Hough matrix generated by that function is not integers.

I'm not sure to what I should do, do you have any idea?

Thx in advance,

Try fitPolynomialRANSAC if you have the Computer Vision Toolbox. It's meant for that kind of thing.

thx, but isn't that only to find 1 fitting line? with hough we can find multiple lines in a single data set/image

Yes. For your file Exchange program, you'd have to ask the author.
