An Improved Fast Edge Detection Algorithm Based on Threshold

In this paper, a novel improved algorithm based on threshold is presented by analyzing Pal.King algorithm systematically. The algorithm proposed in this paper simplifies the complex transformation calculation, and a new enhancement operator is adopted. It proposes a method which determines the optical threshold value based on GA. The experiment indicates that the algorithm is an efficient, universal and valuable image processing algorithm, which can extract general edge.
