摘　　要：为了合成具有高辨识度的素描卡通人脸图像,文中提出一种基于最小二乘法的智能化图像处理算法.文中在介绍最小二乘法的基本原理的基础上,详细阐明了该算法的具体细节,论述了真实人脸图像的预处理过程,建立了合成素描卡通人像的数学模型.同时基于最小二乘法引出了合成算法的误差估计方法,最终提出一种将真实照片转化为素描卡通人像的合成算法.仿真与测试结果表明,文中所提出的算法可以将真实人脸照片转化为具有素描卡通效果的人脸图像,且具有较高的辨识度.In order to synthesize sketch cartoon face images with high visibility,an intelligent image processing algorithm based on least square method is proposed. On the basis of the basic principle of least square method,the concrete details of the algorithm are expounded,the preprocessing process of real face images is discussed,and the mathematical model of compositing the sketch cartoon figures is established. At the same time,the error estimation method of synthesis algorithm is derived based on the least square method. A synthetic algorithm to transform real photos into sketch cartoon figures is proposed. Simulation and test results show that this algorithm can transform real face photos into the face images with sketch cartoon effect and high visibility.
