How to fing COG?

Hi,

How to find the center of gravity of image along the x direction of the line?

Thanks in advance

It's just the usual formula, the sum(x .* intensity) / sum(intensity). It's like the intensity cancels out and you're left with the weighted x value.

How can I do it to all the rows in a image and save it

[Image Analyst]

oneRowIntensity = image2D(theRowYouWant, :);

x = 1:size(image2D, 1);

Then use the formula I gave you, and save it using save() or imwrite() or into a variable. Put that into a loop if you want to do it for all the rows that you want to do it over.
