实现中药颜色客观化表达的研究思路探讨

颜色作为中药一个重要的鉴别属性,是对中药的品种、质量优劣进行快速初筛的基础手段,具有很强的实用价值。但中药的颜色历来表述模糊,难以形成对同一种中药颜色的统一认知,对于中药颜色的客观化表达又由于中药本身纹路的复杂性和各种炮制方法造成的改变的复杂性而迟迟没有进展,因此中药颜色这一重要特征在实际应用中并没有完全发挥其应有的作用。从实际应用的角度,借助图像扫描、背景剔除、边缘提取等现代数码采集和分析技术,对中药颜色的采集和应用方法进行了初步探讨,力求对中药颜色的描述相对客观、准确,且可测量、可比较,使这一中药重要特征发挥更大的实际作用。

Discussion on fulfilling objective expression of color in Chinese medicine

Color, as an important attribute in identifying Chinese medicine, is a basic method for rapid screening of varieties and quality in Chinese medicine. It has a strong practical value. But for the Chinese medicine the color expression is always vague and is difficult to form a unified cognition for the same kind of Chinese medicine color. Also, the objective expression of the color in Chinese medicine has no progress, because of the complexity of texture in Chinese medicine itself and the various existed progressing methods. So this important characteristic of the color in Chinese medicine did not fully play its due role in the practical application. From a practical point of view, with the help of image scanning, background removed, edge extraction and some other modern digital acquisition and analysis technology, this article has conducted a preliminary study on the acquisition and application of color in Chinese medicine, strive to relatively objective, accurately describing the color of Chinese medicine and make that it can be measured and compared, making this important feature of Chinese medicine which can play its practical role greater.
