| 中文摘要: |
| 针对传统三帧差法在运动目标检测过程中存在部分 重叠和轮廓不完整现象,提出了一种结合 Kirsch边缘检测和背景差分的改进三帧差法。算法首先对连续3帧图像进行差分得到运动区 域,然后对 当前帧进行Kirsch边缘检测,通过已得到的运动区域与边缘检测结果进行逻辑“或”运算, 获得完整的运动 目标,利用背景帧差分割运动目标并去除噪声。实验表明,提出的方法能够提取更加完整的 目标区域,有 效避免漏检、误检等情况。与现有一些同类算法相比,本文算法具有更优越的运动目标检测 性能。 |
| 英文摘要: |
| An improved frame difference method on the basis of Kirsch edge detection and background difference is present ed,which is designed for dealing with the overlapped parts and the incomplete object contours in moving objects detection with the conventional fr ame difference.Firstly,the difference of three consecutive frames is used to obtain motion regions,and then the bound ary of current frame is defined by Kirsch edge detection.Finally,the complete mo ving object forms through using motion regions and edge detection for calculatio n with or logic operator.The background difference is applie d to extract objects and eliminate noises.The experiment results prove that the target regions detected by this method are more complete and can effectively avoid the phenomena of “missed” and “false alarm”. Compared with some other algorithms,the proposed method has better performance. |
