Abstract
One embodiment of the present invention provides a system to facilitate variable-loss compression for images of objects in motion in a video system. The system operates by receiving a video stream that includes a sequence of images. The system detects motion between images within this sequence of images. Next, the system determines whether the motion exceeds a threshold value for the motion. If the motion does not exceed the threshold value for the motion, the system compresses the video stream with a compression scheme that has no significant losses. Otherwise, the system compresses the video stream with a lossy compression scheme in order to reduce the bandwidth of the video stream.
Claims24
A method to facilitate variable-loss compression for images of objects in motion in a video system, comprising:
- receiving a video stream, wherein the video stream includes a sequence of images;
- detecting a motion between a first image and a second image within the sequence of images;
- determining if the motion exceeds a threshold value for the motion;
- if the motion does not exceed the threshold value for the motion, compressing the video stream with a first compression scheme;
- and
- otherwise, compressing the video stream with a second compression scheme, wherein the second compression scheme includes a lossy compression scheme.
A computer-readable storage medium storing instructions that when executed by a computer cause the computer to perform a method to facilitate variable-loss compression for images of objects in motion in a video system, the method comprising:
- receiving a video stream, wherein the video stream includes a sequence of images;
- detecting a motion between a first image and a second image within the sequence of images;
- determining if the motion exceeds a threshold value for the motion;
- if the motion does not exceed the threshold value for the motion, compressing the video stream with a first compression scheme;
- and
- otherwise, compressing the video stream with a second compression scheme, wherein the second compression scheme includes a lossy compression scheme.
