An Improved Fast Image Fuzzy Edge Detection Algorithm Based on Optimal Threshold Value

On the basis of comprehensive analysis of limitations of Pal.King algorithm,a new improved algorithm of fast edge detection is presented.The algorithm proposed in the paper simplifies complex transformation calculation in Pal.King algorithm,and a new enhancement operator is adopted.In order to overcome disadvantages of Pal.King algorithm in subjection degree threshold value setting,a new method of subjection degree threshold optimal value determination based on PSO algorithm was proposed.Emulational experiment shows that the algorithm is an universal and practical image processing algorithm,by which image edge can be gently and continuously detected.
