Abstract
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.
Claims6
A computer-implemented method for processing images having texture, the method comprising:
- Using a processor to perform the following steps:
- identifying similar texture regions in a video sequence;
- extracting texture from the similar texture regions to obtain a video sequence with the texture removed and texture parameters wherein a resulting video sequence with texture extracted is represented by an equation in which a first background region is unmodified and a second background region is modified by texture extraction, wherein the texture parameters are represented by a reference value C*, which represents an extracted texture and a color;
- and
- encoding the video sequence with the texture removed.
