I'm trying to run a 2D gaussian function on a specific mask area but with no luck.
I use bwlabel command to select the first area:
I have multiple mask area so if I want to apply the gaussian function for the first three area what I sould write? and how to apply the gaussian function?
Kind Regards,

Apply the blurring function to the whole image, then multiply the mask by the blurred image.

I do not know what the calculations are for density profile.
For histogram, run the histogram on Image(Mask) since histograms do not care about the spatial order of the data.

"I want to apply a 2d gaussian function on the left one and the right one I want to apply different function." <== Wow, you're not making this easy are you? Not sure why
  1. you're not telling us the two functions
  2. there are two different functions
  3. you're not telling us if the image is gray scale or color, and
  4. you're not atttaching the image that is to be filtered
  5. you're delaying an answer by not giving us everything we need up front to help you.

Hi, I really appreciate your help and I already said that I want to apply it on "2D gaussian function" which is a gray image see your quoted reply. similar to this
just to be cleared I want to know how to run any function if I have already mask region but I don't want to apply it to all of them I want to select 2 region or any specific number of masked region.
