The relation between the entropy of an image domain and the entropy of its subdomains is explored as a uniformity predicate. Such entropy is obtained from the analysis of the image histogram associating a Gaussian distribution to the maximum frequency of gray levels. <\/jats:p><jats:p> In order to implement the model, we have introduced a well-known technique of Problem Solving. In our model, the most important roles are played by the Evaluation Function (EF) and the Control Strategy. The EF is related to the ratio between the entropy of one region or zone of the picture and the entropy of the entire picture, while the Control Strategy determines the optimal path in the search tree (quadtree) so that the nodes in the optimal path have minimal entropy. <\/jats:p><jats:p> The paper shows some comparisons between ISE and classical edge detection techniques. <\/jats:p>","DOI":"10.1142\/s0218001498000397","type":"journal-article","created":{"date-parts":[[2003,7,17]],"date-time":"2003-07-17T08:25:53Z","timestamp":1058430353000},"page":"677-693","source":"Crossref","is-referenced-by-count":6,"title":["Edge Detection"],"prefix":"10.1142","volume":"12","author":[{"given":"S.","family":"Vitulano","sequence":"first","affiliation":[{"name":"Institute of Internal Medicine, Medical Clinic \"M.
