Abstract This paper analyzes the essence of a sort of algorithm on image enhancement with fuzzy sets, presents the concept of the bounded histogram and applies them to the sonar image enhancement with fuzzy sets of a small target on the sea bed. The realizing process and experimental results on image enhancement with fuzzy sets are given. The concept of histogram is one of the most important basic concepts in digital image processing. The concept of the bounded histogram presented in the paper will develop the concept of histogram.
