利用DOA和TOA对运动辐射源的单舰无源定位(Using a single passive location DOA and TOA ship moving emitter)

针对杂波环境下的多个机动目标跟踪问题, 本文将多模型概率假设密度 (Multiple-model probability hypothesis density, MM-PHD) 滤波器和平滑算法相结合, 提出了 MM-PHD 前向 – 后向平滑器. 为了避免引入复杂的随机有限集 (Random finite set, RFS) 理论, 本文根据 PHD 的物理空间 (Physical space) 描述法推导得到了 MM-PHD 平滑器的后向更 新公式. 由于 MM-PHD 前向–后向平滑器的递推公式中包含有多个积分(By integrating the multiple-model probability hypothesis density (MM-PHD) filter with the smoothing al- gorithms, an MM-PHD forward-backward smoother is proposed in this paper for tracking multiple maneuvering targets in clutter. To avoid use of complex random finite set (RFS) theory, the backward updated equation of the MM-PHD smoother can be derived according to the physical-space explanation of the PHD)

基于二维直方图的最大模糊熵阈值图像分割，相比于一维最大模糊熵，分割效果更好。隶属度函数采用S函数(Based on two-dimensional histogram maximum fuzzy entropy threshold image segmentation, compared to one-dimensional maximum fuzzy entropy segmentation better)

一个基于形态学图像细化的程序，处理效果挺不错的(Morphological image thinning based on the procedures)

基于小波变换的水下图像目标检测论文加matlab实现代码(Wavelet-based underwater image target detection papers plus matlab code)

说明：  基于MATLAB平台下，可获取图片任意点的像素坐标。(Based on MATLAB platform, the pixel coordinates of any point in the picture can be obtained.)

广义高斯概率分布函数的指数估计，包括矩估计和最大似然估计，并对这两种估计进行了比较(exponential cosfficients estimation for generalized Gaussian pdf，include moment estimator and Maximum Likehood estimator. )

双峰法是一种简单的阈值分割方法，即如果灰度级直方图呈现明显的双峰状，则选双峰之间的谷底所对应的灰度级作为阈值分割。(Two peaks is a simple threshold segmentation method, that is, if the gray level histogram showed a clear bimodal shape, then choose between the two peaks corresponding to the bottom of the gray level as threshold segmentation.)

说明：  可完成对MODIS09GA数据的批量格式转换与裁剪(Batch format conversion and clipping of modis09GA data)

与坐标相关的阈值也叫动态阈值、局部阈值、自适应阈值，局部阈值法：自适应图像分割。(Threshold associated with coordinates, also called dynamic threshold, local threshold, adaptive threshold, local threshold method: adaptive image segmentation.)
