检测前跟踪 粒子滤波 概率假设密度 高斯混合粒子 平滑(Pre-test tracking particle filter probability hypothesis density Gaussian mixture particle smoothing)

说明：  这是基于Camshift的目标跟踪code，编程语言为matlab。下载解压后可以直接运行。(This is the target tracking code based on CAMSHIFT, and the programming language is matlab. After downloading and decompressing, you can run it directly.)

提出一种基于特征点的运动场景图像拼接算法。基于相似变换消除选取在运动物体上的特征点，并使用RANSAC算法进行外点的剔除。在融合阶段，根据齐次变换矩阵求得对2幅图像的差异图像，并执行区域增长算法。从而分割出运动区域。使用一种分段映射算法生成全景图像。实验证明了算法的有效性。(A feature-based algorithm for image mosaics of 8c宅Iles with moving objects is pI．oposcd．The algorithm eliminates the feature points which arc selected in moving objects using similarity transform，and the outliers are eliminated using RANSAC algorithm．In the image blend phase，a difference of two images is created using homogeneous transformation matrix，and a region growth algorithm is implemented SO as to segment the movmg object region．A piecewise mapping algorithm for generating panoramic images is used．Experimental results show the effectiveness of the algorithm．)

粒子滤波与PHD多目标跟踪比较，三目标分别进行粒子滤波和marginalPHD滤波跟踪比较结果。(PHD particle filter multi-target tracking compared with the three goals were to filter tracking particle filter and marginalPHD comparison.)

说明：  遥感图像运用6S工具来进行大气辐射校正处理(Atmospheric Radiation Correction Processing Using 6S Tool for Remote Sensing Images)

医学图像大部分都是dicom图像，这里提供dicom图像读取、显示和保存的matlab代码，以为医学图像处理初学者提供学习。 (Dicom medical images are mostly images, here to read dicom image, display, and save the matlab code, provided that the medical image processing for beginners to learn.)

用其中一半的数据采用ANN-BP算法设计分类器，另一半数据用于测试分类器性能。(Half of them with the data ANN-BP algorithm design classifier, and the other half data used to test the performance of classification. )

本段代码的功能是通过滤波器对细胞图像先进行预处理，然后再提取细胞中心实现细胞的追踪，准确率比较高。(This code is the function of cells through the filter of the first pre-process the image, then extract the cell center to achieve cell tracking, accuracy is relatively high.)

图像的采样 • 写程序：以2 为尺度，下采样图像 ，观察不同分辨率下图像的变化情况(a) • 写程序：把(a)中获得的图像，进行上采样处理，可以选择不同的平滑方 法，比如，邻近像素复制，或者线性插值等。讨论上采样后图像的质量变 化。找出相应的改进方法。
