椭圆圆拟合

指纹图像预处理程序，包括分割，二值化，去噪和细化(Fingerprint image pre-processing procedures, including segmentation, binarization, denoising and refined)

此程序采用vc++6.0编写,可以实现4路视频采集,压缩以及编码(编码算法包括mpeg2),采用的采集卡是天敏vc4000,利用回调函数作为采集的主要手段 另外提供网络传输的服务端程序(This program uses a vc + +6.0 preparation, can achieve 4-channel video capture, compression and encoding (encoding algorithm including mpeg2), using capture card is Mortimer vc4000, use the callback function as the primary means of collection additionally provides end network transport services program)

) 使用分块的主成分分析方法(PCA)对人脸图像进行压缩编码。针对PCA方法计算量大的缺点,首先把问题转化成奇异值分解(SVD)问题,然后设计了特征空间的更新算法,通过递推,简化每一步计算的计算量,达到了实时编码的要求。 4) 在Windows平台下基于Video for Windows(VFW)接口开发了人脸视频图像编码和解码的实验系统,该系统实现了图像采集、图像显示、编码、解码等功能。() The use of sub-blocks of principal component analysis (PCA) on the human face image coding. PCA method for large defects, first of all the issues into a singular value decomposition (SVD) problem, and then design a feature space of the update algorithm, recursive, simplifying the calculation of the amount calculated at each step to achieve real-time encoding requirements. 4) In the Windows platform based on Video for Windows (VFW) interfaces, the human face image coding and decoding video experimental system, the system achieved image acquisition, image display, encoding, decoding functions.)

本人收集的BM3D资料，包括文献，代码，实验效果图，希望对大家有用(I collected BM3D information, including documentation, code, experimental results map, want to be useful)

1、读取显示所给PET图像（SE2IM210）。 2、学习imhist函数，画出所给PET图像的直方图。 3、根据直方图为该PET图像选择合适的显示窗（imshow参数），使胸 部轮廓等解剖结构可见。 4、根据直方图选择合适阈值，分割肿瘤区域与正常区域，计算肿瘤区 域内图像灰度均值、方差、最大值及最小值。(1 give PET images displayed, read (SE2 IM210). 2, learning, imhist function, draw the give PET image histogram. 3, according to the histogram for the PET image to choose the appropriate display window (imshow parameters), make bosom Outline of anatomical structures such as visible. 4, according to the histogram, choose appropriate threshold segmentation tumor area and normal area, calculating the tumor area In the domain of image grayscale average and variance, the maximum and minimum values.)

灰度双线性插值，缩放图像。可以对图像进行几乎无损的小倍数放大，倍数大时有损。(Gray bilinear interpolation, zooming the image. Can be almost non-destructive image to enlarge small multiples, multiples of large detrimental.)

内含完整基于图像处理的缺陷检测源代码，可以直接运行(Including a complete defect detection based on image processing source code can be directly run)
