hi i'm new in matlab. I want to find the number of holes in each connected component prior to hole filling. I know the euler number that returns the number of holes in an image as a whole, but i want to find the number of holes in each connected component individually. any help would be appreciated.

No it doesn't do the whole image. It does it on a blob by blob basis. Just check out regionprops(). The Euler number is just like any other blob-specific measurement you can ask it to make.

"Returns a scalar that specifies the number of objects in the region minus the number of holes in those objects."
Normally the number of objects in the region is 1. So a solid object would have an Euler number of 1. An object with 1 hole would have an Euler number of 0. An object with 2 holes would have an Euler number of -1.
I see only one object in your image with more than 1 or 2 holes, are you expecting those numbers for more than one or two blobs?
