some fast feature extraction algorithms are addressed for joint retrieval of images
compressed in JPEG and JPEG2000 formats. In order to avoid full decoding, three fast algorithms that
convert block-based discrete cosine transform (BDCT) into wavelet transform are developed, so that
wavelet-based features can be extracted from JPEG images as in JPEG2000 images.

camshift_matlab_ilekoaiq
cashift_matlab,我做的一些修改：
1.修改了之前网上的那种需要输入avi文件名再读取的方式，改成直接读取avi文件。
2.修改了另外建立avi文件的方式。
2.实时显示跟踪结果。
3.彩色图显示，用红色框圈出目标。
4.因为是基于颜色特征的，所以要选色颜色特征明显的。你可以自己拍摄目标颜色突出的avi视频来测试。
5.程序结束时有点小问题，按ctrl+c结束。(cashift_matlab, I made some changes:
1. Modify the kind of network before you need to enter the avi file name and then read the way to read avi file directly.
2. Modify the other way to create avi file.
2. Real-time display tracking results.
3. The color map shows the target with a red box.
4. Because it is based on the color characteristics, so to choose the color characteristics of the obvious. You can test your own avi video with a prominent target color.
5. A little problem at the end of the program, press ctrl + c to end.)

SAR滤波MATLAB程序
孔径雷达图像固有的相干斑噪声严重降低了图像的可解译程度，影响了后续目标检测、分类和识别
等应用。因此，SAR图像的相干斑抑制问题一直是SAR图像应用的重要课题之一。一个理想的去斑算法应该在平
滑的同时保持图像的边缘等细节不受损失，目前存在各种各样的算法，但没有一种方法能够完美的满足这一要求。
本文对SAR图像的相干斑抑制问题进行了全面系统的研究，分析了相干斑的形成原因，总结了目前存在的相干斑
抑制算法的主要思路，介绍了具有代表性的算法，并对各种算法的性能进行了定性分析和比较，给出了去斑算法定
量评估方法(The inherent speckle noise of the aperture radar image seriously reduces the degree of interpretation of the image, and affects the detection, classification and recognition of the subsequent targets.
And other applications. Therefore, the problem of speckle suppression in SAR images has been one of the most important topics in the application of SAR images. An ideal speckle algorithm should be flat
At the same time, the details such as edges of images are not lost. There are various algorithms at present, but none of them can satisfy this requirement perfectly.)
