Paper Abstract

Scene input,restoration, and extraction are discussed. An input model portrays the sampled scene as corrupted by additive Gaussian noise. The effect of this noise upon gradient-square and Laplacian boundary extraction operations is reduced by minimization of a pre-specified loss function. The loss can be related to the efficiency of the system. An adaptive area extraction pro-cedure based upon a gray level thresholding technique is also developed. The threshold is locally adjusted to meet varying background gray-level ranges. Results of computer simulations illustrate visually characteristics of the extraction approaches considered.
