Abstract
A video data compression method, medium, and system. The video data compression method, medium, and system includes receiving image data, generating background model data of the image data, determining a moving object region based on the image data and the background model data, estimating a motion value of the moving object region, and compressing the image data by referring to at least one of the background model data and the estimated motion value.
Claims26
A video data compression method, comprising:
- generating background model data of image data;
- determining a moving object region based on the image data and the background model data;
- estimating a motion value of the moving object region;
- and
- compressing the image data using at least one of the background model data and the estimated motion value.
At least one medium comprising computer readable code to control at least one processing element to implement a video data compression method, the method comprising:
- generating background model data of image data;
- determining a moving object region based on the image data) and the background model data;
- estimating a motion value of the moving object region;
- and
- compressing the image data by using at least one of the background model data and the estimated motion value.
A video data compression system, comprising:
- a background model generation unit to generate background model data from image data;
- a moving object determination unit to determine a moving object region based on the image data and the background model data;
- a motion estimation unit to estimate a motion value of the moving object region;
- and
- a compression unit to compress the image data using at least one of the background model data and the estimated motion value.
A video data compression method, comprising:
- generating background model data from a first frame of a surveyed area;
- detecting movement of an object within a frame subsequent to the first frame of the surveyed area, considering the generated background model data;
- and
- encoding the object as a Region of Interest (ROI) if the detected movement meets a predetermined threshold.
A video data compression method, comprising:
- determining a differential image by calculating a difference between at least two sequential images;
- calculating a differential motion saliency for blocks of the differential image;
- determining a set of blocks of the differential image with the calculated differential motion saliency meeting a threshold;
- and
- generating a moving object region based upon linking the determined set of blocks of the differential image for encoding an image other than a background image corresponding to the two sequential images.
