| 3. | It exploits the consecutive temporal and spatial dependencies of the points on a track to distinguish them from background clutter 它主要是运用了目标运动在时间利空间上的连续性来积累目标能量。 |
| 4. | According to the statistic characteristics of ir background clutters , a system based on improved spatial matched filter ( smf ) is presented in this article 本文在总结前人研究成果的基础上,针对复杂背景红外图像的统计特性,提出了一种基于组合式空间匹配滤波器的运动小目标检测方法。 |
| 5. | The main function of radar is target detection in the background clutter . the effect of clutter to the automatically detecting system is one of most important problem which could not ignore in the radar design 雷达的主要目的就是在存在干扰的背景中检测出有用目标,杂波对雷达检测性能的影响一直是雷达设计中不可回避的重要问题之一。 |
| 6. | In the forth and back windows , the mosos - cfar detector uses the ordered statistics as the background cutter power level of the two windows , and the sum of the forth and back local estimation as the total estimation of background clutter power level Mosos - cfar检测器在前后滑窗分别采用有序统计量来表示前后滑窗的背景杂波功率水平,再将前后局部估计相加作为总的背景杂波功率水平估计。 |
| 7. | The experimental results identify that this process can robustly track and classify targets of interest , reject background clutter , and continually track objects over large distances despite occlusions , appearance change , and cessation of the target motion 实验结果表明,该过程能够很好地探测和分类目标,去除背景信息的干扰,并能够在运动目标部分被遮挡、外观改变和运动停止等情况下连续地跟踪目标。 |
| 8. | Compared to other shape matching algorithms , our shape modeling and detection algorithm has distinguishing features . our part - based and hierarchical strategy finds each part of the shape sequentially , rather than extracting all shapes from the image to match with the possible shape models . it can improve the accuracy and speed the detection processing , and can help to reduce or eliminate the effects of background clutters , partial occlusions and inner rotation in the object 形状建模和检测算法与一般方法相比,具有鲜明的特点,即不需要先提取形状再与可能的目标模型匹配,而是采用分部分和分层次的处理思想,依次在图像中搜索形状的各个组成部分,由此提高了检测的精度和效率,减小或消除了复杂背景、部分遮挡和目标内部组成部分旋转的影响,同时可以实现并行处理。 |
