| 摘 要： | 针对大量瑞氏染色细胞图像, 通过YCbCr颜色空间进行K-means聚类, 观察各分量聚类中心差值变化规律, 提出了一种新的确定K-means聚类数的颜色校正算法。该算法首先是将瑞氏染色细胞图像中不同目标分别准确地聚集在相应类当中, 再与标准图像中的每类进行配比, 并利用直方图规定化进行直方图调整, 得到颜色校正结果。经大量实验证明, 尤其在细胞图像中目标颜色特征较接近的情况下, 该算法通过确定合适的聚类数可大大提高颜色校正结果的准确率。

| Abstract: | To observe the changing rule of clustering center’s value in K-means by the YCbCr color space, against a lot of cell image by Wright Stain, this paper proposed a new method to determine the number of clusters in K-means to get a good result of color correction. Different target of cell image could be firstly gathered in the corresponding class accurately, then by matching between classes, and using histogram specification for adjusting histogram, the results of color correction could at last be achieved. It has been proved by many experiments that this algorithm can greatly improve the accuracy of color correction results, especially the target with closer color features in cell. |
