ABSTRACT:
An image segmentation system segments images into component elements by modelling the image as a series of combined layers. The brightness of pixels within each layer is modelled as a parametric function of pixel position. Weights are assigned to each pixel position within each layer and describe how the layers are combined to form a recovered image. By modelling the image as a compilation of layers having different brightness functions, the system segments elements within an image, including text, when the image is corrupted by noise and when elements are combined, such as text and graphics. Enhanced image compression is obtained by modelling the image in multiple layers.
