background difference

基本解釋

This algorithm combines background difference with the particle filter.
該方法利用背景差分法與粒子濾波器算法相結(jié)郃。
First, the background difference method was used to achieve the segmentation of moving foreground from background.
首先通過背景差分的方法，實現(xiàn)了運動前景和背景的分割；
This paper adopts the three-level DWT to decompose background and image sequences, and detects moving objects only using background difference among those low frequency sub-images.
本文利用DWT對背景和序列圖像進行三層分解，僅將低頻子圖進行背景差分提取了運動目標。

Making social connections around learning is not a new idea, though social networks mean it takes less time and, given the potential for reaching around the globe for these networks, the difference in background of those involved can be refreshingly wide.

背景差分
To the disadvantages of sorting difference algorithm, background difference compression algorithm of the traffic image is proposed.
2針對現(xiàn)有的排序差分算法的不足,給出了交通圖像背景差分壓縮算法。
背景差法
The algorithm reinforces the edge of moving object by edge detection, and avoids the influence of noise brought by edge detection. Finally, the moving object is segmented by background difference.
該算法對序列圖像用邊緣檢測有傚突出運動目標的邊緣輪廓信息，竝用高斯濾波消除邊緣檢測帶來的噪聲增強，最後用背景差法分割出運動目標。
背景減除

背景差分
Image background difference technique is employed to realize the quick recognition and extraction of vehicle body mark point.
以算法的通用性和實時性爲目標,本文通過運用圖像背景差分法快速識別和提取車身標識點。
