Abstract: Several embodiments of a media processor for the creation of metadata from a set of images are given. The media processor receives a set of image data and computes metadata from the image data. The metadata may comprise statistical data based on the image data; from which the media processor may generate and store a multi-scale version of the metadata. The metadata may comprise statistical attributes derived directly from the image data or statistical attributes derived from image appearance correlates of the image data. The media processor may generate a subsampled set of the metadata and the subsampled set may be stored in an efficient data structure, such as a pyramidal structure. The pyramidal structure may be generated from spatial image information, from temporal image information or from spatial-temporal image information.
