Description: 数字图像传输是图像编码与压缩技术的另一个重要应用领域。随着现代社会对通信业务要求的不断增长，图像通信和通信网容量的矛盾日益突出。特别是具有庞大数据量的数字图像信息更是难以传输和存储，极大地制约了图像通信的发展，已经成为图像通信发展中的瓶颈。图像压缩技术的应用为传真、视频点播、电视会议、医用图像传输等领域带来了巨大经济效益。快速压缩解压缩算法及其硬件结构在实时视频系统中起着关键的作用。
-digital image transmission of image coding and compression technologies Another important application areas. As modern society to the requirements of the communications business continued to grow, image communication and communication network capacity contradictions are becoming more prominent. Especially with the huge amount of data digital image information more difficult for transmission and storage, has greatly restricted the development of image communication, image communication has become a bottleneck in development. Image compression technology for the application by fax, video-on-demand, video-conferencing, transmission of medical images and other areas has brought huge economic benefits. Rapid compression and decompression algorithms in hardware for real-time video system plays a Platform: |

Description: 分形用于图像压缩编码,分形编码非常费时，大部分时间浪费在给每个range块寻找合适的domain块，但如果减少搜索domain块的范围，编码速度将有很大提高。所以编码时用快限制分形编码,把图像分成4小块，每块中的range块只在这块中寻找domain块。-for fractal image compression coding, fractal coding is very time-consuming, most of the time wasted in each range block to find a suitable domain block, But if the search domain blocks to reduce the scope of coding speed will be greatly improved. So fast coding using fractal coding restrictions, the image is divided into four small pieces. every piece of the range block only find in this domain block. Platform: |

Description: This a JPEG encoding & decoding program of still image. It does not use level shifting. Discrete Cosine transform (DCT) is performed both by classical & Chen s Flowgraph methods. Predefined JPEG quantization array & zigzag order are used here. RUN - LEVEL coding is used instead of Huffman coding. Compression ratio is compared for each DCT method. Effect of coarse and fine quantization is also examined. The execution time of 2 DCT methods is also checked. In addition, most energatic DCT coefficients are also applied to examine the effect in MatLab 7.4.0 R2007a. Input is 9 gray scale pictures & output is 9*9=81 pictures to compare. Blocking effect is obvious.

Description: 首先到sun下载最新的jmf，然后安装。http://java.sun.com/products/java-media/jmf/index.jsp
然后，说一下需求
1． 用摄像头拍照
2． 在文本框输入文件名
3． 按下拍照按钮，获取摄像头内的图像
4． 在拍下的照片上有一红框截取固定大小的照片。
5． 保存为本地图像为jpg格式，不得压缩画质
技术关键，相信也是大家最感兴趣的部分也就是如何让一个摄像头工作，并拍下一张照片了。
利用jmf，代码很简单：
-First of all to the sun to download the latest jmf, and then install. http://java.sun.com/products/java-media/jmf/index.jsp Then, say something needs one. Photographed with the camera 2. In the text box to enter the file name 3. Press the camera button, and get the image within the camera 4. In the photographs taken on a red box interception of fixed-size photos. 5. Saved as a local image as a jpg format, no compression technology, the key to quality, I believe and the most interesting part is how to make a camera work, and captured a picture of. Use jmf, the code is very simple: Platform: |
