- 基于局部像素块的Retinex机制实现自动白平衡
- 在200张病理切片图像上验证，优于传统摄影白平衡方法
- 特别适合苏木精-伊红和免疫组化染色图像
光学显微镜下获取准确、色彩平衡的图像对经验丰富的操作者仍具挑战。本文提出一种完全自动的白平衡校正机制，可有效修正显微图像色彩。算法在200张显微图像上实验验证，涵盖病理形态学中常用的三种组织样本。结果与数字摄影中常用的白平衡算法对比，表明该方法在苏木精-伊红及免疫组化染色图像上的表现更优。
原文摘要 · Abstract (English)
The acquisition of accurately coloured, balanced images in an optical microscope can be a challenge even for experienced microscope operators. This article presents an entirely automatic mechanism for balancing the white level that allows the correction of the microscopic colour images adequately. The results of the algorithm have been confirmed experimentally on a set of two hundred microscopic images. The images contained scans of three microscopic specimens commonly used in pathomorphology. Also, the results achieved were compared with other commonly used white balance algorithms in digital photography. The algorithm applied in this work is more effective than the classical algorithms used in colour photography for microscopic images stained with hematoxylin-phloxine-saffron and for immunohistochemical staining images.
