    摘要： A method and apparatus for deriving a representation of an image is described. The method involves processing signals corresponding to the image. A two-dimensional function of the image, such as a Trace transform (T (d, ϑ)), of the image using at least one functional T, is derived and processed using a mask function (β) to derive an intermediate representation of the image, corresponding to a one-dimensional function. In one embodiment, the mask function defines pairs of image bands of the Trace transform in the Trace domain. The representation of the image may be derived by applying existing techniques to the derived one-dimensional function.

    摘要： A method for deriving a representation of an image is described. The method involves processing signals corresponding to the image. A three dimensional representation of the image is derived. The three dimensional representation of the image to used to derive the representation of the image. In one embodiment, each line of the image is defined by a first parameter (d) and a second parameter (ϑ), and a position on each line is defined by a third parameter (t), and the three dimensional representation is parameterised by the first, second and third parameters. A set of values is extracted from the three dimensional representation at a value of the first parameter, and a functional is applied along lines, or parts of lines, of the extracted set of values, the lines extending along values of the second or third parameter.

    摘要： A method for encoding a descriptor of multimedia content, in which the descriptor includes a plurality of components describing respective parts of the multimedia content comprises processing the descriptor to determine a priority of the plurality of components, and encoding the components of the descriptor based on the determined priority.A method of decoding the descriptor comprises decoding a predetermined number of the plurality of components, by decoding each of the components in the priority order. Advantageously, the encoding and decoding techniques enable fast, scalable searching.
