Abstract: A method of generating a matte for an image is disclosed. The method includes, with a processor, receiving image data representing the image, with the processor, selecting one or more objects represented in the image data, with the processor, generating an intermediate matte based on the selected objects, and with the processor, generating one or more splines based on the intermediate matte, where at least one of the selecting of the one or more objects, the generating of the intermediate matte, and the generating of the splines is performed by an artificial intelligence system. The method also includes, with the processor, receiving instructions to modify the generated splines, with the processor, generating modified splines by modifying the generated splines according to the received instructions, with the processor, generating training data based on the modified splines, and with the processor, training the artificial intelligence system with the training data.
