说明：  对脑肿瘤进行分割 基于3dunet(Brain tumors were segmented based on 3dunet)

说明：  基于matlab的语音信号处理快速傅里叶变换程序(Fast Fourier Transform Program for Speech Signal Processing Based on MATLAB)

针对目前工业制造领域面临的难题,提出利用非量测数字摄像机进行工业钣金件高精度三维重建与视觉检测.采用二维直接线性变换分解摄像机参数初值并结合光束法平差进行高精度标定 利用最小二乘模板匹配提取像面上的点、直线信息并进行混合光束法平差,从而进行钣金件的高精度三维重建及其尺寸制造误差的检测.所开发的视觉检测系统硬件成本低、自动化程度较高,实际数据的多次实验均取得了优于1/8 000的相对精度,说明所论述的方法为工业零件的自动化三维检测提供了一条可行途径.(View of the current challenges facing the field of industrial manufacturing, made use of non-metric digital camera precision sheet metal parts for industrial reconstruction and visual inspection. Using two-dimensional direct linear transformation and the decomposition of initial parameters of the camera bundle adjustment with high accuracy calibration extracted by the least square template matching, like the surface of point, line information and mixed bundle adjustment to the three-dimensional reconstruction of high-precision sheet metal parts and the size of the detection of manufacturing errors. visual inspection system developed by the hardware low cost, high degree of automation, the actual data, many experiments have achieved better than 1/8000 of the relative accuracy, that the methods discussed in the automation of industrial components to provide a feasible three-dimensional detection approach.)

说明：  用平方根算法进行矩阵的优化，以便使用卡尔曼滤波获得精确的值(kalman filter and pingfanggen method ，using it can obtain accurate value )

将保存有灰度图像信息的txt文件转化生成灰度图片。 txt数据只能包含数据，数据用逗号或者空格隔开，所存数据个数应与所生成的图片大小相同。例：要还原的图片大小为640*480，那么txt文件中就应当有307200个数据。(The txt file with information of grayscale image is transformed into gray image. The TXT data can only contain data, separated by commas or spaces, and the number of data stored should be the same as the size of the generated image. Example: the size of the image to restore is 640*480, so there should be 307200 data in the txt file.)

图像的相关系数是衡量两幅图像的相关程度的，本代码直接通过选定区域计算出相关系数！(image correlation coefficient is a measure of two images of the code directly through selected regional correlation coefficient calculated!)

边缘检测的各种经典算法，很值得一看。机会不容错过。快来看呀。(edge detection algorithm for the classic, is an eye-catcher. The opportunity should not be missed. Come see ah.)

gabor小波变化的实现，用于数字图像处理中Gabor特征的完全提取。自己项目中已经用到了。(Achieve gabor wavelet transform for digital image processing totally Gabor feature extraction. Himself has used the project.)

说明：  图像处理中，一种新的边缘检测，特征点提取方法，算法经过测试，可以运行，对医学图像处理的人有帮助(Image processing, a new edge detection, feature point extraction method, the algorithm has been tested, you can run on the medical image processing to help the people)

说明：  lsb数字水印算法，SB算法利用了数字图像处理中位平面的原理,即改变图像的最低位的信息,对图像信息产生的影响非常小,人眼的视觉感知系统往往不能察觉。以一幅256灰度的图像为例, 256 灰度共需要8 个位来表示,但其中每一个位的作用是不一样的,越高位对图像的影响越大,反之越低的位影响越小,甚至不能感知。(Digital watermarking algorithm based on lsb)
