为了提高图像倾斜矫正的效率和准确率，提出了一种基于三阶Cartesian矩的图像倾斜快速矫正算法。首先改进图像二值化处理技术，将图像划分为若干部分，并且在不同部分提取特征线，对其进行二值化处理；然后求解Cartesian矩的三阶矩阵模型，利用其计算目标图像在图像尺度矫正、图像旋转矫正和倾斜图像平移矫正的模型。实验仿真表明，本文算法具有较高的准确率，且执行效率高。

In order to improve the efficiency and accuracy of the image tilt correction, tilt rapid correction algorithm based on third-order the Cartesian moment the image. First improved image binarization processing techniques, the image is divided into several parts, and to extract the characteristic line, and in different parts of its binarization process; then solving a the Cartesian moments third-order matrix model, the use of the calculation of the target image in the image scale. correction, image rotation correction and tilt image translation correction model. Simulation results indicate that the proposed algorithm has high accuracy, and the implementation of high efficiency.
