  corner feature
This paper presents a robust 'corner feature extraction' algorithm which extracts corner features of binary image without any assumptions and constraints.
      
The chosen landmark is defined by eight line segments which intersect at eight corner feature points.
      
Therefore, we search for the nearest corner feature as the control point in a preset range.
      
Once we have found the corner feature, we can use it and its original reference location to update the position and orientation of the robot.
      
If there is no corner feature found, we will not start the prediction process.

A fast recognition algorithm is presented for interesting region extraction of an object based on corner features. Two direction code chains of boundary elements are obtained through forward and backward boundary tracking, and a corner is determined by the code chains. The dominate part of the object can be extracted by using prior information of corner distribution on the digital image. The algorithm suggested herein can be performed on a parallel basis. The simulation results proved it to...

本文给出了一种基于角特征的目标兴趣区的识别算法。通过对二值图象边缘点的向前和向后K步跟踪,可以得到该点两个方向的方向链码,而一个角则由该两个方向链码确定。然后根据已知目标上角分布的先验信息,将目标的主体提取出来。本文给出的算法可并行实现。计算机模拟结果表明,该算法是有效的。

To present a method for the recoqnition of moving object based on corner features。Therecognition of moving object requires more attention than stationary or slowly-moving ob-ject,it requires nonsensitivity on scale, direction varying and object moving.

运动目标的识别比起静止或变化缓慢的目标识别具有更严格的要求,即要求对方位、比例因子的变化及目标的运动等因素不敏感。讨论了运动目标识别的不变矩方法后,提出了基于角特征的运动目标识别的方法。

The image contour is segmented into lines, arcs and smooth curves by median filtering of extended direction code. Based on this segmentation, a set of new local invariant features are proposed to recognize partially occluded objects, which is more reasonable compared with conventional corner features. The matching results of some typical examples shows that these features are robust ,effective in recognition.
