静止背景 meaning in English
static background
Examples
- Serial images can be divided into two types by which background is still or moving
由运动目标所形成的图像序列可分为两种情况：一种是静止背景，一种是运动背景。 - There are many reports in the first type and these reports mostly base on frame subtraction and background modeling
静止背景运动检测现有研究较多，主要是采用帧间差法和背景建模法。 - In this paper we use the gait database which each sequence has only one person walk in the same background . two background modeling methods are studied : rgb and gray , comparing the two methods , we chose the first which is more effective
首先,从步态序列图像中检测步态,本文采用的是静止背景下的单人步态数据库,研究了rgb空间和灰度背景建模方法,经过性能比较我们选取了前者。 - Then the noise is removed by means of the variance that is estimated directly from the median of the noise . finally , an auto - detection is made for the motion displacement from the difference image undergone the above pre - processings
本文给出的方法以散射图去除光照影响和静止背景，用噪声的中位数直接估计其方差，从而去除噪声，检测出由运动引起的变动，最后自动检测运动距离。 - Considering the weakness of the optic flow approach , we give an improved object detection and segmentation method in the moving background case . afterwards , two practical factors , which bring negative effects , are discussed in detail : lighting variation and camera dithering
在对静止背景情况充分研究的基础上，本文着重分析了基于光流估计的运动背景目标检测和分割方法，并对光流估计精度不高时的目标检测和分割提出改进方案。
