小波变换具有良好的“时间—频率”局部化特性及多尺度变焦距特性对于二维图象的小波变换,其梯度模值提供了图像的边缘信息在大尺度时,图像边缘稳定,但存在有位移小尺度时,边缘定位精确,但易受噪声影响噪声和边缘都具有较高的空间频率噪声的能量小,在大尺度下,其小波变换系数值小边缘的能量大,在大尺度变换下,其小波变换系数值大由多尺度小波变换系数的变化情况,估计边缘的类型采用多尺度小波变换系数作为
用一种新的基于轮廓形状分析的工程图识别方法,可有效地处理段线、模糊线、字线粘连等多种退化图纸的情况,既可以精确获得线的逼近,也可抽取图纸的整体图形结构针对工程图的特性给出了局部图像特征的数学描述,并将其作为区域分类的特征依据扫描图像的三层中间描述用于低质量图纸的识别,基于轮廓曲率的一种直线抽取技术用作这种中间描述
江西省植物生理学会于1999年3月27~28日在临川市抚州地区农校召开了4届4次理事扩大会。讨论并通过了该学会1998年度工作总结和1999年学会工作计划;传达第6次全国作物栽培生理在庐山召开的学术讨论会情况;评选出1998年度优秀学术论文;商讨筹备...
Studies have demonstrated that there are two types of PSI (PSI-1 and PSI-2) particles in some higher plants. These two types of PSI particles are proved to differ in organization and distribution on t
采用一些传统算法压缩三维图形数据时,发现压缩比虽高,但是在压缩过程中很容易忽略那些相对于整体变化细微而局部变化激烈的子区域,而且对于曲线的微小变化很敏感,以致于重建效果不理想。本文以曲率作为判据,克服了上述缺点,能对于上述区域尽量加以保留。实验数据表明,压缩后的重建效果较为理想。
