【摘要】 针对传统图像边缘检测方法检测效果不理想的问题,利用四元数的矢量旋转原理,将一种改进后的粒子群优化算法引入四元数图像边缘检测中,提出一种新的彩色图像边缘检测方法。实验结果表明,该方法对彩色图像的边缘检测效果较好,能够提取图像纹理细节,且算法稳定、容易收敛,边缘检测速度也较快。更多还原

【Abstract】 Because of the traditional edge detection inadequacy,quaternion’s vector rotating theory is used,improved particle swarm algorithm is introduced to quaternion edge detection.A new color image edge detection method is presented.Experimental results show that the proposed method of color image edge detection has good effect.It can extract the image detail,and the algorithm is stable,easy to convergence,edge detection a little faster.更多还原
