Claim 8:
9. A system for image matting, the system comprising:
one or more processors to control and/or execute a deep neural network (DNN) configured to generate an alpha matte associated with an image comprising image pixels, wherein the alpha matte is generated based on a user-specified foreground region location in the image, and wherein the DNN includes
a first subnetwork configured to generate a trimap associated with the image based on (a) a binary mask associated with the image and (b) the user-specified foreground region location, the trimap designating at least some of the image pixels as at least one of background, foreground, or uncertain status; and
a second subnetwork configured to generate the alpha matte based on the trimap and the user-specified foreground region location;

wherein the DNN is further configured to generate a color decontamination map that provides color channels associated with pixels of the alpha matte, wherein the color decontamination map is either a foreground color decontamination map that provides foreground color channels, or a background color decontamination map that provides background color channels.
