Hi all,

Regionprops can calculate the areas of the blobs in binary image. When considering the binary image as a logical array, how does the regionprops() calculate the area of a single blob? (Is it using the number of pixels in the blob or using some other method?).Can some one give me a reference to study those kind of stuff.Thanks.

Regards
Prasanna

It's the number of pixels. See the ComputeArea subfunction of
regionprops.m. Or the doc:
