摘　　要：在分析了现有图像变形方法的基础上,提出了一种基于扫描线的图像变形方法。首先指定原始图像的特征轮廓并获得特征轮廓的控制点,然后对控制点进行调整得到目标图像的边界约束,采用给出的扫描线算法对边界约束内部进行像素填充,得到变形图像。解决了变换过程中像素点的选取问题,更重要的是保证了变形后的图像颜色与原始图像变化趋势相同。An algorithm of image deformation based on scan lines is presented. Firstly, the feature outline of the initial image is specified and a set of control dots of the feature outline is computed. These control dots are adjusted to get a contour constraint of the destination image. The inner part of the contour constraint is filled with color of the initial image to get the result image by using the scan line algorithm. The problem of selecting pixels is solved in the process of translation, and it is more important to keep the color of destination image according to the initial image.
