基于四元数的彩色图像边缘检测研究

Abstract

In order to achieve color image edge detection,the paper establishes color image automatic edge detection algorithm.The paper describes the color image representation based on the quaternion, achieves the color image edge detection algorithm based on snake operator.First,the paper describes color image edge detection according to the three primary of color images,the vector quaternion representation and quaternion basic computing methods.Second,the basic principles of snake operators and detection process are introduced.Finally,the paper constructs the dual quaternion operator and snake color image edge detection algorithm.The experimental results show that it can retain its original image information by using the color image edge detection algorithm and the edge information is intake.The color image representation based on the quaternion can basically satisfy stability and reliability,complete information,strong anti-interference ability and other requirements.
