灰度级变换 meaning in English
grey level transform
Examples
- The generalized fuzzy enhancement method extend the gray level range of the original image , and a canonical form of membership function in the stage of fuzzy enhancement is presented which remains the advantages of the original fuzzy enhancement and the gray level transformation while transforming the membership function of the gray scale to [ 0 , 1 ]
这种新的图像增强方法包括三个阶段，即图像滤波、模糊增强和灰度级变换，扩大了原始图像灰度等级的范围，在保留了原有模糊增强方法和灰度变换优点的同时，规范化了模糊增强环节中灰度隶属度函数的形式。 - In the motion detection a method which is based on time and space is used for it can detect harmful invade object in spite of surroundings inteferre . in addition , after got the image of objects , the rectangle frame technique is used to fill the hole . in my design another part is multi - objects image tracking which is a new technique and it integrates image processing , automatic control and computer science . this technique can automatically acquire objects from image signal , get objects " position information then track them with the aid of dome
本文中提出了若干有价值的新思想、新方法，完成了以下内容：首先，提出了数字视频监控的功能结构，描述了数字监控系统的组成、特点和发展现状；然后研究了适合于跟踪监控的摄像机坐标系，提出了一种双角度摄像机坐标以适合本系统的实际应用；讨论现场图像的预处理，其中包括灰度级变换、噪声滤波和图像恢复；在运动监测中，比较了几种常用的运动检测方法的优缺点，提出了一种基于时域和空间域的图像检测方法；另外，在得到运动物体的图像时，采用矩形框技术填充由于差分图像造成的孔洞，此方法简单可靠，有较大的实用性。
