You cannot do that. MATLAB only supports rectangular (well, hyperdimensional cuboid) arrays. You cannot end up with, for example, a circular array.

The closest you can get is to crop at the bounding box of the shape.

it is possible by introducing a mask of particular shape and filtering image through it .
