| 目的 研究色域映射中色域边界的描述方法。 方法 在均匀区域分割法的基础上提出一种基于阈值的非均匀区域分割算法,通过调整阈值和分割数量, 对不同类型图像的色域边界进行均匀描述。 结果 使用较少的边界点准确地描述色域边界,并且边界点的空间分布均匀,没有出现大量边界点集中的情况。 结论 通过与均匀区域分割法对比,该算法可用较少的采样点和分割数目精确地描述色域边界,对实现从图像到设备的色域映射有重要意义。 |

| Objective To study the gamut boundary description in the color gamut mapping. Methods A method of non-uniform segmentation with local threshold segmentation was proposed based on the uniform segmentation method. By changing the threshold and segment numbers, the gamut boundary of images of different types could be uniformly described. Results It could use fewer boundary points to describe the gamut boundary, and show better coverage of the gamut surfaces. There was no centralized gamut boundary points around the gamut surfaces. Conclusion Through comparison with the uniform segmentation method, this algorithm could accurately describe the gamut boundary with fewer boundary points and lower segmentation numbers, which is beneficial for developing the image-to-device gamut mapping algorithm. |
