形状 form; appearance; shape; fashion; likeness 保持它的形状 keep [hold; retain] its shape; 所有圆的形状都是相同的。 all circles have the same shape. 汽车的形状已有很多改进。 there have been many improvements in the form of cars
信息交换用图形字符点阵形状 matrix font of graphic characters for information interchange
The effect of implied shape of objects on picture recognition 物体隐含的形状信息对图片再认的影响
The no . 1 , 3 , 4 , 5 harmonic in the spectrum based on radius represent almost all shape information of apples 用幅长方法得到的频谱,其1 , 3 , 4 , 5次谐波就基本上能够包含苹果的形状信息。
Because of its commonness , uniqueness , reliability and also arrti - interference , this technology has high acadeimic valur and very wide future applications 受技术的限制,当时的虹膜识别主要依据颜色和形状信息,而且信息通过人的观察获取。
Ieee trans . pattern analysis and machine intelligence , 1997 , 19 : 696 - 710 . 5 cootes t f , taylor c j . statistical models of appearance for computer vision 新定义的纹理既保留了原始的形状信息又保证了定长表示的要求,同时这样定义的纹理完全决定了形状的信息。
Next , this paper describes a new feature - based method using edge information of typical objects combined with local gray - level statistical information to image - to - image registration 在此基础上,本文提出一种结合局部灰度信息与边缘形状信息的基于特征的sar图像配准方法。
Meanwhile , objective to the requirement of both real - time and accuracy for moving shaped target detect and tracking , a novel method is proposed based on combination of images difference and feature invariant . the paper improved the tradition difference method , constituted a feature invariant which characterized the object contour without influence of object ’ s size change , shifting , and rotation , and developed a dynamic - extremum - matching scheme 同时,针对识别跟踪具有形状信息的大飞行器目标所提出的快速准确要求,提出了一种基于改进的差分算法与特征不变量匹配的目标识别方法,弥补了传统图像差分方法的不足,构造了一个具有平移、大小和旋转不变性的特征不变量用于识别目标,并研究出一种动态极值匹配方案。
All of above make the miss distance of the missile difficult to estimate in shooting range . in order to solve these problems , a novel method for detecting and tracking small moving point target in image sequence is proposed in this paper , based on combination of the correlation of multi - frames and wave gate techniques . especially , the qualifications to confirm the target and the establishment of the wave gate based on size and characteristic moving parameters of the target are stressed in the paper 针对目前靶场所面临的测量目标小、距离远、目标与背景对比度小,不具有形状信息的实际问题,提出了一种基于多帧相关技术与波门选通技术相结合的快速目标识别与跟踪方法,特别探讨了多帧相关技术中目标确定的理论判据,并综合考虑目标的尺寸因素和目标的运动特征研究了一种新的波门设定方案。
One distinct difference between mechanical and architectural drawings is , views , which express one type of functional components , are not in one paper , in general , when all of the views is in the same paper , the methods aim at mechanical drawings such as engineering drawing computer understanding or " the 3d reconstruction " can be used in architectural drawings 建筑图样和机械图样的一个显著区别是:反映建筑物功能部件形状信息的平、立、剖面图时常不在同一张图纸中。论文第三章从功能部件的视图表达方式入手,分析了面向功能部件图形信息完整表达的不同种类施工图组合形式,归纳出了功能部件的视图关联特征,提出了基于视图关联的工程量信息获取方法。
