Hi,
I want to get one information regarding center of mass to get the center of
particles in a image.
to get it I need to do *Image>Adjust>Threshold.
*which makes my gray image to binary.*
*Therefore If I analize the particle to get center of mass It does not give
weighted average grayscale center of mass,
rather gives centroid ( just average of the pixel position). Is there any
procedure so that I can get center of mass of the particles, which
is the brightness-weighted average of the x and y coordinates all pixels in
the image.

Thanks N Regards
