帧间差 meaning in English
frame-to-frame differences
Examples
- 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 uncompressed domain , we analyse the processing and the normal algorithms of scene change detection . a new algorithm for video abrupt shot change detection based on the relation of the partial interframe differences is proposed in this dissertation
在解压域,系统地分析了解压域镜头边界检测过程和常见的解压域镜头边界检测算法,提出了一种新的解压域镜头突变检测算法:基于局部帧间差相关性的镜头突变检测法。 - 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。 - We propose a simple and fast scheme to detect moving object in complex background which is the combination of inter - frame difference , morphologi - cal filter and optical flow field . it ' s simple and fast to detect moving object using inter - frame difference . however , it ' s lack of precision and moving information
在众多的运动目标检侧算法中,我们将帧间差值法、数学形态学方法、光流场方法加以结合,提出了一个简单快速的复杂背景下多目标运动区域检测与分割算法。 - In temporal segmentation a statistical model is used to automatically separate the moving areas from the background in a general video sequence . the spatial segmentation bases on the results of temporal segmentation and using region - growing algorithm in rgb space can locate precise boundary of moving object . lastly , using segment moving object as the initial model , moving object can be tracked by matching an image to a model based on hausdorff distance on a sequence of video , and the model is updated every frame to accommodate for changes in shape
时间分割中采用连续帧间差的统计假设检验，确定运动对象的位置，自动地分离出运动区域与背景区域；空间分割中则采用基于颜色的区域增长算法来精确地提取运动对象的轮廓；最后，将提取到的运动对象作为模板，对后续的视频序列，用基于hausdorff距离度量匹配，来跟踪并提取后续帧中运动对象。
