All you need to do is draw a rough approximation of the edge of the object and tell Decompose what the foreground and the background are.
所有您需要做的是制订一个粗略的逼近边缘的对象，并告诉分解有什么前景和背景。
When Easterners take in a scenes, they tend to focus more on the context as well as the object: the whole block, say, rather than the BMW parked in the foreground.
当东方人游览景观时，他们往往既记住物体，又同样关注环境。比如说，他们既关注停在前景的宝马车，也同样关注整个街区。
For this movie Orson Welles, along with cinematographer Gregg Toland, pioneered "deep focus", a technique that keeps every object in the foreground, center and background in simultaneous focus.
在拍摄本片时，奥逊·威尔斯和摄像师格雷戈·托兰发明了一种非常现代的拍摄方法：“深焦镜头”。
After studying particle filter technology, a moving object tracking algorithm based on a particle filter was developed, integrating foreground information, color features and an integral image method.
通过粒子滤波技术，研究了如何整合颜色特征、前景信息和积分图运算等技术实现视频目标跟踪的粒子滤波算法。
The result of experiment shows that this algorithm can pull foreground video object from a complicated background effectively.

The distribution of improved LBP texture is discussed and a significant test is performed to classify each moving pixel into foreground object or moving shadow according to this theory.
通过分析阴影的物理模型，得出局部纹理的光照不变性，利用基于比值判决的LBP纹理法来区分运动车辆和阴影，并应用亮度约束和几何启发式准则进一步改善阴影检测效果。
