图形学程序，有一些画图的程序，全部都是自己编写的源码，有一些来自于清华大学出版的《计算机图形学》-graphics procedures, some drawing procedures, all prepared by the source itself, some from Qinghua University, published in the "Computer Graphics"

论文主要介绍了JPEG的编码和解码过程。该程序的编码部分能把一张BMP格式的图象进行JEPG编码，压缩成以二进制形式保存的文件；通过相应的解码程序又可以把图象解压缩出来。在图象传送过程中，我们经常采用JPEG格式对静态图象进行编码。JPEG基本系统是一种有损编码，无法完全恢复出原图象，信息有一定的丢失，称为有损压缩。尽管我们希望能够无损压缩，但是通常有损压缩的压缩比(即原图象占的字节数与压缩后图象占的字节数之比，压缩比越大，说明压缩效率越高)比无损压缩的高。JPEG编码先把图象色彩RBG变成亮度Y和色度Cr、Cb，它利用人的视觉对色度不敏感的特点，减少一部分色度数据，以达到压缩。 JPEG采取多种编码方式，包含有行程编码(Run Length Coding)和哈夫曼(Huffman)编码，有很高的压缩比。在编码前，先对数据进行分块，离散余弦变换（DCT）及量化，保留能量大的低频信号，丢弃高频信号以达到压缩。解码时，进行熵解码，反量化，反离散余弦变换（IDCT）。

学习VC也没多久，将我做的这个小工具和大家分享一下。其主要功能就是可以自定义生成公章图形并保存为bmp图片，希望对大家有点用。具体实现的方法如下： 步骤一：生成对话框工程，并加入相应的控件，图片的显示使用Picture控件； 步骤二：定义生成图形所需要的参数； 步骤三：通过参数定义，生成对应的Bitmap，再在Picture控件中显示该位图，具体实 现参看源程序。 步骤四：将生成的Bitmap保存为位图文件。 -VC did not learn how long I will do this small tools and share with you. Its main function is to be generated from the definition graphics and seals for the preservation bmp picture, and I hope to use you a bit. The specific methods to achieve the following : Step 1 : Generation dialog, and add the corresponding controls, the pictures showed a picture control; Step 2 : definition graphics generated by the parameters; Step 3 : through the definition of parameters, generate the corresponding Bitmap, and the Picture Control showed the bitmap, See achieve specific source. Step 4 : Generation to preserve the Bitmap bitmap file.

A novel texture-based Automatic Fingerprint Authentication System (AFAS) is proposed. A fingerprint image is preprocessed to enhance the image by Short Time Fourier Transform (STFT) analysis. Then, three sets of invariant moment features, as a kind of texture features, are extracted from three different sizes of Region of Interest (ROI) areas based on the reference point from the enhanced fingerprint image. Each set of invariant moments contain seven invariant moments. Fingerprint verification is realized by Euclidean distance between the two corresponding features of the test fingerprint image and template fingerprint image in the database. -A novel texture-based Automatic Fingerprint Authentication System (AFAS) is proposed.
