| 摘 要： | 传统图像旋转算法存在颜色失真和锯齿边缘的现象，为此，分析最近邻插值模型和曲面拟合模型，提出一种基于移植理论的图像旋转算法。该算法利用调色板信息避免颜色失真，借鉴移植理论消除锯齿边缘现象。实验结果表明，与最近邻法和曲面拟合法相比，该算法得到的图像轮廓清晰、边界分明，峰值信噪比较高。

| Abstract: | To avoid the rotation of the color distortion and jagged edge of the phenomenon and analysis of the neighbours interpolated models and fitting model of surfaces, an algorithm of image rotation based on the migration theory is presented. The method employs the color palette information to avoid distorted information color, and diminishes the phenomena of jagged edge. Experimental results show that the algorithm gets the image’s outline more clear compared with nearest neighbor methed and fitting model of surfaces methed. Its PSNR is higher than that of nearest neighbor method and fitting model of surfaces method. |
