I need to create two pixel patches of size 5×5 with constant intensity values μ=150 for X location and η ∈[0,255] for Y location, and then comparing this pixel patch pixelwise with image by the squared l2-distance(Euclidean distance). Comparison of the pixel patches over the one image should perform 10,000-times for every value of η∈[0,255]to fortify this experiment with sufﬁcient statistics.

Then I need to create a plot of this experiment that shows the average distance of the two pixel patches and the standard deviation.

Any help how can I do it in matlab?

The desired result is like attached file.

The image is dicom(ultrasound img). In fact, I am following an experiment on the paper attached link on page 5. Maybe my understanding is wrong. The pixel patch on (x,y) location with intensity(150,[0,255]) should scan over the image. paper
