摘要: A method of representing and analysing images comprises producing a plurality of descriptors of an image at one or more scales and for one or more colour channels, said descriptors capturing colour content and interrelation information within the regions, and associating the descriptors in a plurality of ways based on their characteristics such as scale, colour channel, feature semantics, and region, and comparing such representations of images to assess the similarity of images.

摘要: A method and apparatus for processing a first sequence of images and a second sequence of images to compare the first and second sequences is disclosed. Each image of the first sequence and each image of the second sequence is processed by: (i) processing the image data for each of a plurality of pixel neighbourhoods in the image to generate at least one respective descriptor element for each of the pixel neighbourhoods; and (ii) forming an overall image descriptor from the descriptor elements. Each image in the first sequence is compared with each image in the second sequence by calculating a distance between the respective overall image descriptors of the images being compared. The distances are arranged in a matrix, and the matrix is processed to identify similar images.

摘要: A method of processing a sequence of video frames to determine whether a wipe transition exists between shots of the sequence comprises, for each video frame, calculating its differences from a previous frame using the colour and spatial position information of the pixels in the current frame and the previous frame, projecting the differences onto one or more projection axes or other bases, calculating a measure of the likelihood that an abrupt shot transition has taken place for each of a plurality of points on a projection based on the projection value at each point for a plurality of frames including the current frame, and detecting wipes by detecting characteristic geometric patterns in the temporal sequence of the said measure of likelihood in one or more projections.
