suppose we have a silhouette of a person (image of a person represented by white color and the background is black). write a matlab code to determine the number of white pixels forming the person in that silhouette?

A silhouette is the image of a person, an object or scene represented as a solid shape of a single colour, usually black, its edges matching the outline of the subject. The interior of a silhouette is featureless, and the whole is typically presented on a light background, usually white, or none at all. The silhouette differs from an outline which depicts the edge of an object in a linear form, while a silhouette appears as a solid shape.
