What is the difference between centroid and weighted centroid in regionprops?

Which one of the two calculates the center of gravity of the entire image. Thank you.

'WeightedCentroid' will use the pixel intensities in the image region as weights in the centroid calculation. With 'Centroid', all pixels in the region get equal weight.

Is weighted centroid the center of gravity of the image? Thank you.

[Image Analyst]

Yes, you could think of it that way.

Is weighted centroid the center of gravity of the image?

If the pixel intensities are the "mass" of the image, then yes.
