This study aimed at the shortcomings of existing fixation algorithms that are image-based only, and an effective tea fixation state monitoring algorithm was proposed. An adaptive filtering algorithm was used to automatically filter the ineffective information. Using the energy extractor, the complete energy information of each fixation image was extracted. The image energy attention mechanism was used to identify the prominent features, and based on these, the energy data was mapped to generate the data points as the training data. The cluster idea was adopted, and the training data feed the features trainer. The trend center data of the tea processing energy clustering was generated from different color channels. The corresponding decision function was designed which is based on the distance of the cluster center. The fixation degree of each monitoring image set was measured by the decision function. The Euclidean distance of the energy clustering center of the three channels with the same fixation time progressively approached. The triangle formed by these three points had a trend of gradually shrinking, which was first discovered by us. The detection results showed high accuracy compared with the common classification algorithms. It indicates that the algorithm proposed has positive guiding and reference significance.
本研究针对现有基于图像的固定算法的缺点,提出了一种有效的茶叶固定状态监测算法。采用自适应滤波算法自动滤除无效信息。利用能量提取器,提取每个固定图像的完整能量信息。使用图像能量注意机制识别突出特征,并基于这些特征对能量数据进行映射生成数据点作为训练数据。采用聚类思想,将训练数据输入特征训练器。从不同颜色通道生成茶叶加工能量聚类的趋势中心数据。根据聚类中心的距离设计相应的决策函数。根据决策函数测量每个监测图像集的固定程度。具有相同固定时间的三个通道的能量聚类中心的欧几里得距离逐渐接近。这三个点形成的三角形逐渐缩小,这是我们首先发现的趋势。与常见的分类算法相比,检测结果显示出较高的准确性。这表明所提出的算法具有积极的指导和参考意义。
