Hi,

I work in image analysis, and the program that I work on is doing the following 2D / 3D image profile. I could do that, but I need to scatter one column in the image or one row in the image I mean by scattering is scattering the intensiy maximum only in either the column or row . So I want to extract one column or one row.

One of the suggestions that I worked on is using ginput to select the column intensities then scattering, which is works but is not an accurate method.

Another method that I worked on is using the result of find peaks function from the plot of image profile of the column or row but that does not help :)

Last mothed is using imregionalmax and manually reading all the pixels then scattering the result. It is time-consuming.
