智能太阳能Led虫情测报灯用来研究基于图像处理的水稻害虫的分类识别和计数,并对水稻害虫的虫情状况进行预测。该系统利用太阳能作为电源,利用光波诱捕害虫,并对虫体进行图像采集,图像处理,图像特征提取,并运用图像分类识别技术,对害虫进行分类和虫体识别,实现人工智能化,同时能有效杀死水稻害虫,提高水稻产量。智能太阳能Led虫情测报灯集害虫诱杀、测报、种类调查于一体,是害虫防治最为理想的选择,符合国家可持续...
为了提高全自动固晶机视觉系统中发光二极管(LED)晶片边缘特征的提取精度,提出了一种基于改进非极大值抑制(NMS)过程和双阈值求取方法的Canny边缘检测算子。传统的非极大值抑制过程,直接将中心像素点与梯度方向周围邻近的2个像素点进行比较,易导致边缘信息不准确。针对该问题,结合中心像素点本身及其梯度方向周围的3个像素点,沿着梯度方向进行双线性插值,从而实现改进的非极大值抑制过程;另外,通过对LED...
对CHES 2011会议提出的轻量级分组密码LED抗功耗模板攻击能力进行了评估,从功耗曲线预处理优化的角度对模板攻击提出了改进:利用功耗曲线频域上的相位相关性计算偏移量,消除了模板构建过程中的数据干扰;利用明文片段对功耗曲线聚类划分的特征差异,提出了一种基于类间距离的特征提取方法,可实现不同泄露点的功耗数据自动切割;利用均值和噪声信息评估模板区分度,提出了一种基于聚类有效度的动态选点策略,提高了旁...
