ALPHAMASK: Overlay image with semi-transparent maskOverlays a semi-transparent mask over an image. By default the currently displayed figure is overlain.Options include overlay colour and opacity.Returns a handle to the overlay mask.Usage: hOVM = alphaMask(bwMask, [colour, transparency, axHandle]) bwMask: logical matrix representing mask colour: vector of three rgb values in range [0, 1] (optional; default [0 0 1]) transparency: scalar in range [0, 1] representing overlay opacity (optional; default 0.6) axHandle: handle to axes on which to operate (optional; default current axes) hOVM: handle to overlay image is returnedExample: figure; I = peaks(200); bwMask = eye(200); imshow(I, [], 'Colormap', hot); alphamask(bwMask, [0 0 1], 0.5);See also IMSHOW, CREATEMASK
