  • Patent number: 8836725
    Abstract: A method of providing an image for display comprises: determining a target image size in terms of first and second dimensions; processing an input image to detect a region of interest therein, the region of interest having first and second dimensions; and providing an image for display by modifying the input image having regard to the first and second dimensions of the target image size and the first and second dimensions of the region of interest in the input image. Also disclosed is corresponding apparatus and a corresponding computer program.
    Type: Grant
    Filed: August 28, 2007
    Date of Patent: September 16, 2014
    Assignee: British Telecommunications public limited company

  • Patent number: 7982762
    Abstract: The invention provides a method and system wherein first video images are directly overlaid with remote video images to produce a combined video image which is then displayed to the user and/or stored as appropriate. Preferably at least one of the first and/or remote images is subject to an image processing operation prior to the overlay operation being performed, the image processing operation being such that the scenes contained within the images to be overlaid when processed are separably distinguishable to a user within the combined video image when viewed by the user. The overlay operation is performed such that the scenes contained within the respective video images are substantially in alignment on top of each other.

  • Patent number: 7646395
    Abstract: Caricatured images of subjects are generated wherein the caricatured image of each subject is adapted when subjects join and leave a closed group of which they are members. By adapting the caricatured images in this manner, it can be ensured that each caricatured image remains maximally distinguishable from the other images in the group, thus ensuring that recognition of the images may be maintained at a high level.

  • Patent number: 7620264
    Abstract: Increased recognizance of caricatured images is provided for the level of caricaturing to be applied to an image to be set in dependence on the intended size of the caricature image. Preferably, the caricature level is set as a generally inverse function of the image size, such that the smaller the image the greater the level of the caricaturing that is applied. In such a case increased recognizance of subjects represented in smaller images may result.

  • Patent number: 7333672
    Abstract: An image recognition process applied to a photograph is preceded by a pre-processing step which identifies parts of the image which are in focus. The recognition process is then limited to those parts. The pre-processing typically operates by creating a measure of high spatial frequency activity and applying a threshold to them.

  • Publication number: 20030053693
    Abstract: An image recognition process (15) applied to a photograph is preceded by a pre-processing step which identifies parts of the image which are in focus. The recognition process is then limited to those parts. The pre-processing typically operates by creating (10-12) a measure of high spatial frequency activity and applying a threshold to them (13, 14).
