detectfaces - Find faces in the image.

Calling Sequence

faces = detectfaces(im)

Parameters

• im: The input image, color or gray image.
• faces: An Nx4 matrix. Each row of the matrix contains information about a face position and size: [x,y,w,h]. (x,y) is the top-left corner coordinates of a rectangle contains a face; w,h are width and height of the rectangle respectively.

Description

The function finds faces in an image.

Examples

    im = imread(SIVP_PATH+'/images/lena.png');
    faces = detectfaces(im);
    [m,n] = size(faces);
    for i=1:m,
        im = rectangle(im, faces(i,:), [0,255,0]);
    end;
    imshow(im);
