多频外差

1. 将真彩位图转化成各色或黑白位图，进行二值化(支持多种抖动方法)处理后的位图，效果和速度极佳。 2. 将真彩或黑白位图进行 90度 , 180 度 ,270 度 高速度旋转。 (1. The true color bitmap into a colored or black and white bitmap to binary (supports multiple dithering methods) treated bitmap, effects and excellent speed. 2. The true color or black and white bitmap to 90 degrees, 180 degrees, 270-degree high-speed rotation.)

通过使用LLE PCA两种方法相结合的思路，提高人脸识别的分别率(LLE PCA by using the idea of combining two methods to improve face recognition rate difference)

稀疏低秩去噪的MATLAB代码，包括OMP算法与KSVD算法(Sparse low rank denoising MATLAB codes, including OMP algorithm and KSVD algorithm)

c源代码 图象的压缩编码，JPEG压缩编码标准 功能是行程编码，JPEG压缩编码（基本系统）(c code, function: jpeg stand for image show)

本例程通过matlab编写，显示一个GUI。在GUI中将输入到程序中的数据进行绘图。本例程能够实时进行绘图，并且可以将数据进行显示。同时还可以将输入到程序中的数据进行保存。在GUI中设置有控制开关，能够通过点击开关，将数据保存在不同的文本中便于后续处理使用。(This routine is written by matlab and displays a GUI. The data input into the program is drawn in the GUI. This routine can be plotted in real time and data can be displayed. At the same time, the data input into the program can also be saved. A control switch is set in the GUI, and the data can be saved in different texts by clicking the switch to facilitate subsequent processing.)

对超声图像的去噪和分割，可以显示肿瘤图像的边缘和面积(For ultrasound image denoising and segmentation, image can show the tumor edge and area)

可用于matlab 人脸检测，准确率较高。(It can be used in matlab face detection, with higher accuracy.)

说明：  图像识别算法，使用点阵方式识别图片，借用Tessnet2.zip 组件，用来进行图片文字/图片数字识别(Tessnet2.zip use to be Image recognise)

图形学中的透视投影算法 在屏幕中心绘制立方体的透视投影 可以绘制一点透视图 二点透视图 三点透视图(Graphics in the perspective projection algorithm for drawing a cube in the center of the screen you can draw a little perspective projection perspective two point perspective three-point perspective)

实现摄影测量中空间后方交会的问题，用以求得像片的内外方位元素(To achieve space resection in photogrammetry issues photograph to obtain the internal and external orientation elements)
