Abstract
A method for enhancing video display of a video surveillance system, comprises: a. receiving a first video image In−1 and a second video image In corresponding to a previous scan n−1 and a current scan n of the video surveillance system, b. determining a backwards displacement vector Dn from image In associating with scan n to image In−1 associated with scan n−1; c. determining a predicted image Jn+1 for scan n+1 based on the backward displacement vector Dn and on the image In corresponding to the current scan n. The method further comprises displaying an image based on the predicted image.
Claims18
A method for enhancing video display of a video surveillance system, wherein said method comprises:
- a. receiving a first video image In−1 and a second video image In corresponding to a previous scan n−1 and a current scan n of said video surveillance system,
- b. determining a backwards displacement vector Dn from image In associating with scan n to image In−1 associated with scan n−1;
- c. determining a predicted image Jn+1 for scan n+1 based on the backward displacement vector Dn and on the image In corresponding to the current scan n,
- the method comprising displaying an image based on said predicted image.
A video enhancing device for enhancing video display of a video surveillance system, wherein the device comprises:
- a displacement vector calculation unit configured to determine:
- a backwards displacement vector Dn from a first video image In−1 corresponding to a previous scan n−1 of said video surveillance system and a second video image In corresponding to a current scan n of said video surveillance system;
- a backwards displacement vector Dn+1 from the second video image In corresponding to scan n of said video surveillance system and a third video image In+1 corresponding to a next scan n+1 of said video surveillance system;
- a displaced image calculation unit configured to determine a predicted image Jn+1 for scan n+1 based on the backward displacement vector Dn and on the image In corresponding to the current scan n, and a predicted image Jn+2 for scan n+2 based on the backward displacement vector Dn+1;
- the device further comprising displaying an image based on said predicted image.
