strong peaks in a matrx

[Nghtcrwlr]

 Hello

I would like to know the meaning of "locations of strong peaks in a matrix". I am having a 2D array. It is actually a transformation of an image. The locations of these peaks correspond to the locations of straight lines in the original image. So what is a possible tip for it? DO i need to find the max n min of the whole matrix .but then it shows only one max and one min point. I need to find the strong peaks in the whole matrix. 

Thanks

Hey,

There is a function doing exactly this within the NI Vision Development Module

However, you will have to implement a kind of edge detection allgorithm to determin this. There should be a lot of documentation about this at the WWW, as far as i know you will need to make a differentiation of the intensities, so your array values and then detect the peaks, which then represent the edges.
