2d multi-peak detector (matrix)

[Gary1wang]

Hi I have the same problem. I am tryin to find the local peaks on the 2d array, any better idea? there are 16 peaks in the array. Any suggestion? I looked through the blog. i could not figure out. 

Thanks

Hi Gary,

after this discussion i decided to use the convolutional method to find peaks over my matrix.

You can decide the right mask to use for convolution.

Since this was an old discussion, i am including an example of the method with a sample matrix (working from LV7.1), where you can find out also the mask that  was working fine for me.

You could execute and check if it works with your values also.

You could modify it in order to finde more local peaks, but the method could remain the convolutional one - i think it is a good way to solve .

best regards
