Abstract
Embodiments provide methods and systems for encoding video including identifying a region of interest and compressing data of the region of interest at a first bitrate.
Claims21
A method of encoding video frames in a bitstream, said method performed by at least one processor of an encoder, said method comprising:
- receiving data for a sequence of images;
- identifying a region of interest in an image, wherein the region of interest is identified by processing at least some of the data according to a visual perception model, the visual perception model comprising at least one of the following:
- perceiving changes in one or more pixels;
- correlating said changes in one or more pixels to one or more factors, said factors comprising a depth of color of one or more pixels and a change of color of one or more pixels;
- compressing data of the region of interest at a first bitrate;
- and
- compressing data of a background region at a second bitrate, the first bitrate exceeding the second bitrate.
4 more elements
A video encoder comprising:
- at least one processor operable to encode video frames in a bitstream;
- the at least one processor configured for receiving data for a sequence of video frames;
- the at least one processor configured for identifying a region of interest in a video frame, the region of interest identified by processing at least some of the data according to a visual perception model, the visual perception model comprising all of the following:
- luminance, motion vectors and salience;
- the at least one processor configured for compressing data of the region of interest at a first bitrate;
- and
- the at least one processor configured for compressing data of a background region at a second bitrate, the first bitrate exceeding the second bitrate.

- and
- the at least one processor configured for compressing data of a background region at a second bitrate, the first bitrate exceeding the second bitrate;
- and
- a communications network for transmitting said bitstream to at least one recipient.
