Extract objects from binary image

Hey,

I am looking for a way to extrac objects from an binary image.

For example, Given the following image, I am looking for a way to get the matrix of the area of each of those 3 big objects.

Thank you in advance.

Something like this perhaps,

BW=bwareafilt(~yourBinarizedImage,3);

regions=regionprops(BW,'Image');

[Walter Roberson]

In particular, regionprops and ask for 'Area'

[Matt J]

Depending on what "matrix of the area" means... To me, it sounds like the sub-image containing the bounding box of the regions.

[Walter Roberson]

I would interpret it as a single matrix containing all three areas.

Areas = [regions.Area];
