The Relax Image Relaxation System: Description and Evaluation

Abstract

RELAX is a system of routines that modifies the probabilities associated with labels attached to the elements of a two-dimensional array. These modifications reflect the compatibility of each element's labels with those of its neighbors. The initial probability assignments are usually derived from local property values in the neighborhood of each pixel. The final assignments may be used for object detection or segmentation, or may be mapped back to image intensities to achieve noise suppression, enhancement, or segmentation. The relaxation package was contributed to the ARPA/DMA Image Understanding Testbed at SRI by the University of Maryland. This report summarizes applications for which RELAX is suited the history and nature of the algorithm, details of the Testbed implementation, the manner in which RELAX is invoked and controlled the type of results that can be expected and suggestions for further development. The document includes both a user's guide to the RELAX system and an evaluation of the algorithm.
