Paper Abstract

An eigenstructure approach for the region detection is presented in this paper. It first defines Block and Snapshot, followed by the data formulation. A covariance matrix is formed as an overall description of the entire image environment. Then information criteria are finally applied to directly determine the number of regions. This approach does not make the heuristic assumptions for the model and considers the spatial correlation among the pixels. it also provides faster and more accurate operation than model-based approaches. The principle of block processing is described and the encouraging results are included.
