1. 本研究利用 PCA 对可见-近红外（450～1 000 nm）、可见光（450～780 nm）和近红外（780～1 000 nm）光谱区域的苹果高光谱图像数据进行降维，获得 PC 图像，通过对 PC 图像进行分析，确定可用于分割损伤和正常区域的有效光谱区域，对比分析几个光谱区域的 PCA 的效果。(but currently no practical system for detecting blood spots and dirt stains exists. In order to obtain maximum throughput, processing speeds of over 85,000 eggs per hour are common. The demanding requirements placed on the human workers result in two types of grading errors)
