frame difference meaning in Chinese
帧间差
Examples
- In the thesis , the algorithm of background subtracting , frame difference algorithm , motion estimation based on optical flow field and object tracking based on active shape contour are investigated
本文研究了背景相减算法、差分法、基于光流场的运动估计和基于主动形状模型的目标跟踪算法。 - The frame difference algorithm was used for dealing with the problem of initial background image extracting automatically , and different moving pixels in current image were detected through a subtracting technique
通过一种基于帧间差分的算法，自动提取初始背景图像，并使用相减法，检测出当前图像中的运动像素。 - Compared with the traditional detective methodes based on frame difference , the operation of the method is more less . because the threshold based on noise characteristic parameters is adaptive produced , algorithmic adaptability is better
与传统的基于像素的帧间差分法相比,运算量较小。根据相对噪声的特征参数所估计的相对噪声的阈值是在检测过程中自适应生成的,适用性较强。 - To solve the first problem , frame difference information is used to direct the location of object regions of difference image frame , and then the objects location information come from d i f ference frame i s used to compound a background frame that does not include any moving object
对背景建模问题，文中提出了根据帧差信息指导不同图像帧中的目标物区域位置定位，据此用不同帧目标物区域像素值合成“空”背景的方法。 - Optical flow field contains not only the moving information of the object , but also three - dimensional information . this paper integrates the inter - frame difference and optical flow methods . the method of inter - frame difference is used to separate moving area from the whole image
本文将二者相结合,运动目标的第一步检测由帧间差值法完成,同时运用数学形态学方法对差值图像进行过滤和排查,精确提取出多运动目标的运动区域。
