自抗扰控制技术的matlab仿真

【核心代码】 联合概率数据互联JPDA是数据关联算法之一，它的基本思想是：对应于观测数据落入跟踪门相交区域的情况，这些观测数据可能来源于多个目标。JPDA的目的在于计算观测数据与每一个目标之间的关联概率，且认为所有的有效回波都可能源于每个特定目标，只是它们源于不同目标的概率不同。JPDA算法的优点在于它不需要任何关于目标和杂波的先验信息，是在杂波环境中对多目标进行跟踪的较好方法之一。然而当目标和量测数目增多时，JPDA算法的计算量将出现组合爆炸现象，从而造成计算复杂。程序功能 :采用JPDA数据关联算法实现两个个匀速运动目标的点迹与航迹的关联% 输入变量 :% -target_position: 目标的初始位置% - n: 采样次数 % - T: 采样间隔% -MC_number:仿真次数% - c: 目标个数% 输出变量 :% 无

论文《As-Projective-As-Possible Image Stitching with Moving DLT》中的拼接算法，对于视差图像拼接具有一定的鲁棒性，但是对特征点数量及其分布均匀性有较高的要求。 The success of commercial image stitching tools often leads to the impression that image stitching is a “solved problem”.The reality, however, is that many tools give unconvincing results when the input photos violate fairly restrictive imaging assumptions;the main two being that the photos correspond to views that differ purely by rotation, or that the imaged scene is effectively planar.Such assumptions underpin the usage of 2D projective transforms or homographies to align photos. In the hands of the casual user,such conditions are often violated, yielding misalignment artifacts or “ghosting” in the results. Accordingly, many existing imagestitching tools depend critically on post-processing routines to conceal ghosting. In this paper, we propose a novel estimationtechnique called Moving Direct Linear Transformation (Moving DLT) that is able to tweak or fine-tune the projective warp toaccommodate the deviations of the input data from the idealized conditions. This produces as-projective-as-possible image alignmentthat significantly reduces ghosting without compromising the geometric realism of perspective image stitching. Our technique thuslessens the dependency on potentially expensive postprocessing algorithms. In addition, we describe how multipleas-projective-as-possible warps can be simultaneously refined via bundle adjustment to accurately align multiple images for largepanorama creation.
