Abstract: Apparatus and method for automatic surveillance of a monitored area having one or more regions of interest using a video imaging device are disclosed. The method includes receiving data defining said one or more regions of interest and one or more characteristics of an object of interest; pointing the line of sight of the imaging device at a region of interest selected from said one or more regions of interest; automatically scanning the selected region of interest to detect said one or more characteristics of the object of interest and upon detection issuing an alert; and when said one or more regions of interest includes more than one region of interest, repeating the steps of pointing the line of sight of the imaging device and automatically scanning in a predetermined order of viewing of the regions of interest, and upon detection of said one or more characteristics of the object of interest issuing an alert, for each of the regions of interests.

Abstract: A method for verifying the authenticity and integrity of an ordered sequence of digital video frames, without having access to the original recording, by embedding therein a respective series of digital signatures based on a secret key, or keys, and on the video content of respective frames. Signatures are camouflaged by embedding in transform coefficients of a transformed representation of the video data in parts of the frame corresponding to motion. If there is sufficient motion to contain all of the signature bits, a supplementary technique embeds in high-texture areas of a frame. A final fall-back is to embed in a pre-defined default zone. A method of predicting when supplementary embedding is needed enables the process to be applied in a single pass allowing real-time operation. Verification is done during decoding by comparing, for identity, embedded signatures with signatures calculated anew using the method employed to embed.

Abstract: A method and apparatus for image interpolation provides a simple method that can up-scale an image in various scale ratios, including fractional scaling ratios, and can yield a sharp image with reduced unpleasant visual artifacts. An embodiment uses a power weight function that is gradient dependent and uses a function that has a linear dependence on the distance to compute interpolated pixels. A further embodiment uses a power that can be adapted according to the local contrast of edges.
