Abstract:

Classifying similar, counterfeit and deteriorated slices in Chinese herbal slices plays a vital role in clinical application of Chinese medicine. Traditional manual identification methods are subjective and fallible. And the classification of traditional Chinese herbal slices based on computer vision is superior in speed and accuracy, which makes Chinese herbal slice screening intelligent. Firstly, general steps of Chinese medicine recognition algorithm based on computer vision were introduced, and technical development status of preprocessing, feature extraction and recognition model of Chinese medicine images were reviewed separately. Then, 12 classes of similar and easily confused Chinese herbal slices were selected as a case to study. By constructing a dataset with 9 156 pictures of Chinese herbal slices, the recognition performance differences of traditional recognition algorithms and various deep learning models were analyzed and compared. Finally, the difficulties and future development trends of computer vision in Chinese herbal slices were summarized and prospected.

Key words: Chinese herbal slices, computer vision, image preprocessing, feature extraction, image classification

摘要:

中药饮片相似品、真伪、变质等方面的分类对临床中药应用有着至关重要的影响。传统的人工鉴别方法主观性强、误判率高,而基于计算机视觉的中药饮片分类具有快速、准确等特点,使饮片筛选智能化。首先,介绍了基于计算机视觉的中药识别算法的一般步骤,并分类综述了对中药图像的预处理、特征提取和识别模型的技术发展现状;然后,选取12类相似易混中药饮片分类作为案例研究。通过构建包含9 156张图片的中药饮片数据集,分析对比了传统识别算法和多种深度学习模型的识别性能差异;最后,对计算机视觉在中药饮片应用研究中存在的难点和未来发展趋势进行了总结和展望。
