MULTISCALE DETECTION OF LOCAL IMAGE STRUCTURES

摘要

A method (200) and apparatus (101) for the detection of local image structures represented as clusters in a joint-spatial range domain where the method comprises receiving an input image, having one or more clusters in a joint-spatial range domain, and each of the one or more clusters having a corresponding mode (205). Receiving a set of analysis matrices and selecting through each one of the analysis matrices (206). Using the selected analysis matrix to partition the input image into the one or more clusters and their corresponding modes, and computing a mean, µ, and a local covariance matrix S for each of the corresponding modes of each of the one or more clusters (210). Selecting at least one of the one or more clusters, where each selected cluster has a stable mean and stable covariance matrix across the set of analysis matrices, whereby each of the selected clusters is indicative of a local image structure (220)
