图象处理中的一些经典代码 周长发书上的原代码

ellipse butterworth filter

实现对文本信息的统计后对其huffman编码-realization of the text information after its statistics Huffman coding

可用于图像处理中的傅立叶逆变换子程序，使用fortran编程-Can be used for image processing in the inverse Fourier transform subroutine, use the fortran program

对指纹图像用模板进行滤波的代码，其中包括平滑模板和锐化模板-the fingerprint image with the filter template code, including smoothing and sharpening template template

相机中都需要进行伽马校正，本实验中通过程序caculate_curve.m读入图片0中的灰度值，通过计算得到伽马变换的伽马系数，然后利用伽马系数进行反变换。-Both the need for gamma camera calibration, the experimental procedure caculate_curve.m read into the picture through the gray value of 0, obtained by calculating the gamma-gamma transform coefficients, then use the gamma coefficient inverse transform.

自己编写的图像处理工具，比较全面，包括视频处理，图像融合等，可以作为开发参考-I have written image processing tools, a more comprehensive, including video processing, image fusion and so on, can be used as the development of reference

MATLAB 编写的两种将灰度图二值化（多值亦可）的源程序，并付word说明。-it contains two methods which can change gray image to binary image (or multivalue image )in segments.

4：2：0yuv播放，采用directdraw播放-4:2:0 yuv playback, using DirectDraw player

在VC6.0中的一些基本操作,常常用来进行简单的学习和常规的练习 -in VC6.0 of some of the basic operations, often used for the study and simple conventional exercise

用计算机进行数字图像处理，使用matlab环境，对图像进行增强，平滑与锐化，分割，变换，压缩与编码，是平常实验的好选择。-Using computer digital image processing, the use of matlab environment, enhance the image, smoothing and sharpening, segmentation, transform, compression and encoding, is usually a good choice experiment.
