Fuzzy sets and their applications to cognitive and decision processes
- T. Pavlidis
- Computer Science
- 1 December 1977
By providing a basis for a systematic approach to approximate reasoning, the theory of fuzzy sets may well have a substantial impact on scientific methodology in the years ahead, particularly in the realms of psychology, economics, law, medicine, decision analysis, information retrieval, and artificial intelligence.

- 5 June 1988
A method that combines region growing and edge detection for image segmentation with criteria that integrate contrast with boundary smoothness, variation of the image gradient along the boundary, and a criterion that penalizes for the presence of artifacts reflecting the data structure used during segmentation.
