Abstract

Edge detection is the first step for some boundary extraction and boundary representation algorithms. It has been playing an important role in image recognition and data retrieval problems. For example, in the processing of cancer cell images, once the edges of the cancer cells are detected, the shapes of the cancer cells can be seen more clearly. As the shapes of the cancer cells provide useful information for the medical professionals to decide the types of the cancer cells, thus, the technique helps to reduce the time and improves the accuracy for the diagnosis procedure. This paper proposes a fuzzy approch for edge detction.
