基于激光图像分析的苹果表面损伤和内部腐烂检测(Apple Surface Damage and Inner Decay Detection Based on Laser Scattering Image Analysis)
苹果 损伤 内部腐烂 计算机视觉
2009/8/11
利用波长650nm、功率25mW的半导体激光及计算机视觉技术,初步探讨了利用激光图像分析检测苹果(嘎拉)采后表面损伤和内部腐烂检测的可行性。利用钢球砸伤,模拟苹果在采收和运输过程中受到的损伤;利用微量注射器从苹果底部将15μL(105/mL孢子浓度)的青霉菌液注入果心部位使其腐坏,模拟苹果内部的腐烂。进行激光图像检测试验,结果表明,受损伤后苹果图像像素数S3在36h达到最高值(3964),且在1~...
Dynamic Light Scattering Analysis on Critical Behavior of Cluster Size Distribution of Polyacrylamide and Agarose Solutions near the Sol-Gel Transition Point
agarose percolation dynamic light scattering
2009/7/8
The dynamic light scattering (DLS) method was applied to measure the cluster radii of polyacrylamide and agarose solutions near the sol-gel transition point. In the case of polyacrylamide, primary clu...
