System and method for encoding and decoding using texture replacement
The invention provides devices and methods that process images. The invention processes a received signal representing information of texture and information of an image, which has the texture removed from at least one region. The image information is encoded to obtain encoded information of the image. An output signal is generated representing the texture information and the encoded image information. In another embodiment, the invention synthesizes texture based on the received texture information, decodes received image information, which is encoded, to obtain a decoded image, and then maps the synthesized texture onto the decoded image.
1. A method comprising:
receiving a video sequence having a region with removed texture;
receiving texture parameters associated with the video sequence; and
mapping synthesized texture based on the texture parameters into the region, wherein the synthesized texture differs from the removed texture by dominant texture orientation.
2. The method of claim 1 , wherein the video sequence and the texture parameters are received in different channels.
3. The method of claim 1 , wherein the video sequence and the texture parameters are received simultaneously.
