difference image meaning in Chinese
差别图象
差值图像
Examples
- We make doppler beam sharpening ( dbs ) for the receive signal of every sub - aperture , then make difference image
先对每个子天线接收到的信号进行成像处理，然后利用信号的幅相信息进行对消处理。 - Among the face tracking algorithm , we first use difference image to gain the raw - location , then in the limited position , we use two template matching to tracking face
在人脸跟踪的算法中，采用了在差分图像粗定位的基础上，在一个确定的小范围内利用双模板匹配进行跟踪。 - The change detection process performed by unsupervised techniques is usually divided into three main sequential steps : pre - processing , image comparison ( to generate difference image ) and analysis of the difference image
非监督图象变化检测过程通常可以分为预处理、图象比较(得到差异图象)和差异图象分析三个步骤。 - Image difference is the most direct change detection method for change area extraction , but the gray difference image that is only based on spectral feature is difficult in describing the structure change of an objects
图像差分是实现变化区域检测的最直接方法,但是仅仅根据地物光谱特征差异得到的灰度差分图像难以表征地物局部结构的变化。 - Then the scheme based on red eye effect , difference image and kalman filter is adopted . this paper pay attention to introduce the designing of system , the hardware development for capturing image , and algorithms of detection & tracking of pupil
