New algorithms for contour linkage are proposed to track the object's motion edges as well as detect the disappearance of existing edges of the object in the scene.

同时提出一种基于动态规划的轮廓连接新算法，该算法能在运动区域中跟踪物体的运动边界，并同时检测出场景中位于非运动区域的静态物体边界。

We proposed a biologically motivated model of contour detection, which reduces edges from a texture background, while retaining object contours.

基于此我们提出了一个视觉生理机制的轮廓检测模型，其目的是减少背景纹理的干扰，同时保留感兴趣的对象。

The vertical edges (as the key attribute), the window textures, line segments of roof contour and their relationships are used to locate the buildings.

以建筑物垂直边缘为关键属性，结合窗户纹理和屋顶轮廓直线段属性及它们之间的关系，综合推理出建筑物的位置。
