Video compression system and method using differencing and clustering
First Claim
Patent Images
1. A method for compressing video data in a network system, comprising:
- receiving a current video frame from a video input;
calculating differences between the current video frame and a previous video frame;
processing the calculated differences to capture and isolate distinct clusters of image data for compression;
determining unprocessed difference points in the clusters of image data, thereby eliminating use of motion vectors;
scanning the clusters of image data to locate outer rim nodes surrounding the cluster of image data; and
when the unprocessed difference points are found, marking the points as outer rim nodes surrounding the cluster of image data, and when all of the unprocessed difference points have been found, compressing outer rim data representing the outer rim nodes.

Abstract
A video compression system and method to isolate and capture video data for video compression, thereby eliminating the need for motion vectors and blocks. When data is captured from a video input device, such as a video camera, the data is captured and isolated into clusters of difference image data. The clusters are then scanned, filled, marked, split and blended in in order to compress the video data.
