利用快速傅立叶算法，实现快速离散余弦变换及其逆变换

指纹识别实验平台的预处理部分，对指纹图像进行方向场估计、分割后细化，为提取特征做准备，压缩包中有指纹图像，-Experimental platform Fingerprint Preprocessing of fingerprint images in the direction of the market is estimated that after the partition refinement, in order to extract features of so ready, compressed package in fingerprint images,

并行磁共振成算法GRAPPA，希望对大家有帮助，内有K空间数据。-Generalized Autocalibrating Partially Parallel Acquisitions (GRAPPA)

提供强大的图像处理功能，完全源代码公开， 包括旋转，放大，缩小，自动校正，选择范围，裁剪，自动去除黑边，镜像等等功能。提供技术支持，最适合应用于扫描后的图像处理 开发本控件原本就是应用于扫描后的图像处，方便使用-provide a powerful image processing functions, complete source code is open, including rotating, zooming, narrow, automatic calibration choice, cutting, automatic black border removal, image and so on. Provide technical support, Scanning the most suitable for the development of the Image Processing Control was originally applied to the scanned images, ease of use

robustly fits a homography to a set of putatively matched image points-robustly fits a homography to a set of putat ively matched image points

提出确定灰度图像二值化最佳灰度阈值的两种方法,即“双峰法”和“信噪比统计法”,并论证了这两种方法在微小零件尺寸及形位误差的检测中的实用性和局限性。-gray images made to determine the value of the two best-threshold value of the two methods "bimodal" and "signal-to-noise ratio statistics" and demonstration of the two approaches in micro-size components and configuration error detection of practicality and limitations.

图像处理源码，用于特征提取，里面有可执行程序。-image processing source for feature extraction, there are executable programs.

G.723原版英文参考标准,作为多媒体开发人员必备的参考文献.-G.723 original English reference standards, as a multimedia developer essential references.

我编写的教学用的图象处理实验指导书和VC源码，详细内容看指导书。此外辅助程序可以把一个彩色图象转变为灰度图象，因为实验内容主要是处理灰度图象的；并且辅助程序是基于Windows C编程的，可以籍此更多了解windows编程的核心机理。-I prepared teaching image processing experimental guide books and VC source, the details look to guide books. In addition auxiliary procedures can be a color image into gray-scale images, mainly because the experiments deal with gray-scale images and auxiliary procedure is based on the Windows C programming, you can take to learn more about the core of windows programming mechanism.

此程序段是用于对比度调整的MATLAB算法。-incontrast

图象的检测，模式匹配的c代码，请大家仔细看里面的算法哦，希望会有收获吧。-image detection, pattern-matching c code, please carefully read the inside algorithm Oh, it is hoped that harvest.
