  • IDENTIFYING POINTS OF INTEREST IN AN IMAGE
    Publication number: 20130223729
    Abstract: Points of interest are identified in an image to characterise that image by dividing the image tiles, each tile including adjacent pixels. The position of a pixel with an extremum value is determined or located within each tile and that extremal value is ascribed to the tile. A tile with an extremal value which is more extreme than that of all adjacent tiles is identified; and the position within the image of the pixel with the extremum value in that identified tile is selected as the point of interest.

  • DETERMINING ASPECT RATIO FOR DISPLAY OF VIDEO
    Publication number: 20130194493
    Abstract: The intended display aspect-ratio for video is determined automatically by analyzing an image to identify image blocks resulting from prior block-based processing of the video; comparing horizontal and vertical dimensions of those image blocks with horizontal and vertical dimensions of the image, with black border regions excluded as necessary; and determining from that comparison a display aspect ratio for the video.

  • RE-SAMPLING METHOD AND APPARATUS
    Publication number: 20130094782
    Abstract: An image or other sample processor has a resampling filter adapted to provide output samples at an output sampling frequency which can be selected to be higher or lower than the input sampling frequency. The width of the resampling filter aperture is scaled according to either the input sampling frequency or the output sampling frequency so as to obtain the wider of the two possible filter apertures.
