Video Surveillance System, Annotation And De-Annotation Modules Thereof
First Claim
1. An video surveillance system, comprising:
- an image extraction module for capturing at least a video source to obtain an original image and capturing feature information of said original image;
an image annotation module for embedding annotation information including at least said feature information into said original image, and converting said embedded image into a second image of the same format as said original image;
an image compression module for compressing said second image;
an image decompression module for decompressing said compressed second image; and
an image information de-annotation module for extracting embedded information from said decompressed second image and separating an object image from said annotation information to obtain de-annotation information.

Abstract
A video surveillance system gets a first image from at least a video source, and extracts its image features. It embeds annotation information with at least the image features into the first image, and converts the embedded image into a second image without changing the image format. After having compressed and decompressed the second image, the system extracts the embedded information from the decompressed embedded stream to separate the image and the annotation information, thereby obtaining completely recovered annotation information after a recovery process and an image processing. Because the image format is not changed, the operations on the second image at the rear end of the system, such as compression and decompression, are not affected.
