说明：  实现脉搏波信号心率变异性分析,时域分析，频域分析和非线性分析(HRV analysis of the PPG signals)

协方相关算法获得电子散斑条纹图.带入变形前后两张散斑图片,可得到反映变形等势的条纹图形.(HS side-correlation algorithm to obtain the electronic speckle pattern. Into two speckle images before and after deformation, can reflect the deformation of equipotential stripes graphics.)

说明：  多站拼接后三维激光扫描点云的消冗处理,多站拼接后三维激光扫描点云的消冗处理(After more than three-dimensional laser scanning station splicing point cloud processing eliminate redundant, multi-dimensional laser scanning station splicing eliminate redundant processing point cloud)

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.)

本程序为二值图像的处理。通过一种称为CNED(connectivity number based edge detection)的方法对二值图像进行边缘提取。结果表明这种方法比candy sober 等算子更加精确，效果更好。(This procedure for binary image processing. Through a known CNED (connectivity number based edge detection) method for binary image edge extraction. The results show that this method, such as candy sober than the operator more precise, better.)

图像的自动多阈值分割，可以进行灰度图像的自动分割。(Automatic multi-image threshold segmentation, gray-scale images can be automatically split.)

说明：  SVAG图形库, linux下面运行的图形库程序(SVAG graphics library, linux graphics library running the following procedure)

图像变换 将图象分块(8*8)，作DCT变换，并作IDCT：DCT是一种可分离图象变换，用来图象压缩编码，IDCT用来解压缩(Image transform to image sub-block (8* 8), for the DCT transform, and IDCT: DCT is a separable transform image to image compression coding, IDCT used to extract)
