Early Detection of Slight Bruises on Peaches Using Near-infrared Hyperspectral Imaging Technology
摘要
Abstract
In this paper,the near-infrared hyperspectral imaging technology (900~1700nm) is applied for slight bruises detection on the Beijing-8 peach after 12 hours of the injury occurred .The principal component analysis and independent component analysis algorhtm is used for data dimensionality reduction on the injure region .The median filtering , threshold segmentation and mathematical morphology processing is used for damage region segmentation .60 normal peaches and 60 injury peaches is used in our expeirment for early detection of slight bruises .And the expeirmnt result shows that NIR hy-perspectral imaging technology is effective for early detection of slight bruises on peaches .关键词
