对于离焦图像进行自动对焦的图像判定，通过对一些列的图像，从离焦到对焦再到离焦进行图像分析从而获得对焦图像的图片。(For the defocus image autofocus image determination, through a series of images into focus and then from defocus defocused image analysis to obtain a focused image of the picture.)

说明：  张正相机标定，用c++编程，亲证有用，里面有实际的图片，大家可以直接俄使用(Zhang zheng method it is very useful for camera detecting and it contains many pictures i hope you will get help from it)

计算波导的matlab程序，主要是传输矩阵方法(Waveguide matlab calculation programs)

ostu图像分割阈值算法,对Ostu图像分割最优阈值进行优化处理，极大缩短了搜索图像阈值计算时间，与传统的枚举法Otsu方法相比,在计算时间上具有显著的优点。(ostu threshold image segmentation algorithm for image segmentation Ostu optimal thresholds to optimize the processing, greatly reduces the search image thresholding computation time, with the traditional enumeration method Otsu methods, in the calculation of time has significant advantages.)

一种改进的基于整合空间的模糊聚类的水平集分割方法，分割效果比较好(An improved integration of space-based level set of fuzzy clustering segmentation, segmentation is better )

室内定位的源码，基于指纹定位的算法，把指纹存储在数据库在，然后在在线阶段根据收到的wifi信号，蓝牙信号，手机基站信号作为一个向量与数据库中存储的指纹匹配，匹配距离最短的就是指纹数据对应的位置(Indoor positioning source, location-based fingerprint algorithm, fingerprint stored in the , then in the online stage according wifi signal, Bluetooth signals, cell phone base station signals received as a vector in the matches the stored fingerprint, matching the shortest distance is a position corresponding to the fingerprint data)

说明：  在对多光谱遥感影像进行大气校正处理以后，可以利用K_T变换矩阵对其进行水体提取，该算法效果较好(After the atmospheric correction of the multispectral remote sensing image, the water body can be extracted by using the k transform matrix, and the effect of the algorithm is good.)

用于图像去噪的代码，有模型去噪、双树复小波去噪，希望有帮助。(Code for image denoising, a denoising model dual tree complex wavelet denoising, hope to have help。)

说明：  使用python语言实现多张图像的拼接，并且处理拼接之后的裂缝和黑边。(Use python language to achieve splicing of multiple images, and deal with cracks and black edges after splicing.)

噪声环境下的信号检测算法及matlab算法，高斯环境下，门限检测(Signal detection algorithm in noisy environments and matlab algorithm, Gaussian environment, the threshold detector)
