direction image meaning in English
方向影
Examples
- Fingerprint classification based on direction image
基于方向图的指纹模式分类研究 - Algorithms on fingerprint preprocessing are first studied in unit 3 . point direction image is acquired by using discrete direction method . then block direction image is acquired
采用离散方向法来求取指纹的点方向图,进而用直方图法得到指纹的块方向图。 - An algorithm on separation of overlapped fingerprints based on direction image a critical step in automatic fingerprint matching is to automatically and reliably extract minutiae from the input fingerprint images
<中文摘要> =自动指纹识别系统中指纹自动匹配的一个关键步骤是自动地可靠地从输入的指纹图像中提取细节。 - Third , using singular points and direction image , we class the fingerprint . we dispart four small fields in the center field of the fingerprint image . through the directions of the lines in every small field , we confirm the fingerprint type
基于方向图分类法中将中心区域的方向图分为左上,左下,右上和右下四个子区域,根据各子区的纹线走向来确定指纹类型。 - Image motion compensation ( imc ) is the key technology of high - resolution space camera . image motion speed is seperated into two vectors in image coordinate for the existence of the drift angle : the forward direction image motion speed and the crosswise image motion speed . in fact , drift angle control eliminates the crosswise image motion speed , so it is a part of image motion compensation
在空间照相,由于偏流角的存在,使得像移速度在像面坐标系存在两个分量:前向像移速度和横向像移速度,偏流角控制本质上是消除横向像移速度,因此,偏流角控制是空间相机像移补偿的一部分。
