    摘要: The temporal sampling pattern of a sequence of images that represents a moving scene is classified into classes of temporal sampling patterns including “film”, “video” and “still”. Pixels in each image in the said sequence are classified according to the relationship between signed inter-image pixel-value differences f1 and f2 between that image and, respectively, the preceding and succeeding images in the sequence. An initial classification for each pixel may be refined in accordance with the relative numbers of pixels of the image initially classified into each class.

    摘要: The invention concerns image processing and, in particular, the processing of picture attribute fields for an image. A method of obtaining a new picture attribute field of an image is disclosed in which a picture attribute value at one position is allocated to a new position in the image in dependence upon the value of a parameter, such as luminance data, at the original position and at the new position and/or in dependence on the distance between the original position and the new position. The invention may be used to process picture attribute fields comprising: motion vectors; motion vector confidence; segment labels; depth labels; texture labels.

    摘要: To detect the presence of the left and right constituent images of a stereoscopic image packed within an image frame or within a sequence of image frames, images are unpacked according to each one of said known formats; a candidate measure is formed according to each unpacking and the candidate measures are compared to identify the presence of left and right images packed according to an identified format. The candidate measure may be a low pass filtered measure of the difference between the left and right images and may be a high pass filtered measure of the activity in either the left or the right image.

    摘要: A method of analysing image data to quantify prior block-based processing comprises processing a set of pixel values derived from the image data to generate a spatial difference profile along a line perpendicular to assumed block edges, the spatial difference profile representing differences between values of pixels spaced spatially in a direction parallel to said line; summing the spatial difference profile in a direction perpendicular to that line; measuring inter-maxima distances in the spatial difference profile to a fractional precision in pixel spacing units; and aggregating measured inter-maxima distances to determine a block size.

    摘要: A method of and apparatus for image analysis for picture loss detection in fields or frames in video or film content makes use of different correlation characteristics of picture images and non-picture images to detect picture loss. A measure of self correlation of a plurality of image data samples, and a measure of the correlation of the plurality of image data samples with a mean value are determined, and a positive detection of picture loss is based on a comparison between the two correlation measures.
