基于多尺度区域的图像颜色校正算法

图像颜色校正是多摄像机视觉应用中的一项重要技术。本文提出了一种基于多尺度区域的局部颜色校正算法,主要思想是在参考图像与待校正图像之间建立特征点的对应关系。此算法根据尺度不同的区域内可获得的对应特征点数目不同的特性,在不同尺寸参数对待校正图像进行分割,以得到稳定的特征点对应,进而获取准确的颜色校正信息,提高了颜色校正的准确性和鲁棒性。此外,本文还考虑了局部校正对图像颜色一致性减弱的问题,进行了平滑处理。实验证明,本文所提出的方法能获得较好的校正结果。

The Color Correction System for Images Based on the Multi-scale Region

Color correction for images is one of the important techniques of multi-camera vision applications.In this paper a new color correction algorithm based on multi-scale region is presented.The primary idea of this work is that a corresponding relationship of feature-points is established between reference image and uncorrected image.As different scaled region owns different numbers of feature-points correspondence,stable feature-points correspondence and accurate color correction information could be acquired...
