Abstract: An apparatus and method for extracting an object of interest from an image using image matting are disclosed herein. The apparatus for extracting an object of interest from an image using image matting includes a saliency map generation unit, a trimap generation unit, and an alpha map generation unit. The saliency map generation unit generates a saliency map corresponding to an object of interest inside an input image using a color space probability distribution corresponding to the input image. The trimap generation unit generates meta-trimaps using filters, and generates a trimap by clustering the meta-trimaps. The alpha map generation unit generates an alpha map using the trimap and a matting Laplacian matrix, and extracts the object of interest based on image matting using the alpha map and the input image.
