MATLAB6.5辅助图像处理，很有用，适合于广大学者。(MATLAB6.5 assisted image processing, useful for the general academic.)

本程序实现一个MATLAB辅助工具，你可以借助它，选择plot绘制出的各个图像数据，并且随意拖动它们。另外，它还有两个不同形状任意大小的绘图刷子。你使用这个工具选中点的时候，这些点被高亮，直到释放鼠标。另外你还可以在命令行下面调用这个工具，选择绘制的图像(This program implements a MATLAB aids, you can make use of it, select the plot to draw out each image data, and easily drag them. In addition, it has two different shapes of any size drawing brush. You use this tool to select points, these points are highlighted, until you release the mouse. Also you can call the following at the command line tool, select the image to draw)

通过并行压缩进行二维信号压缩，提出了一种利用并行压缩传感技术对二维信号进行压缩的新方案。根据这个原理，译码器的重新构造可以并行进行。通过对二维信号进行某些排列，可以确保所有列具有大致相同的密度级别，并且可以使用相同的测量矩阵进行采样。这样可以避免二维信号的矢量化，从而大大减小测量矩阵的尺寸。我们证明，如果排列良好，重建均方误差的上限会更紧。为了说明这一方案，我们将其应用于视频压缩并使用不同帧的排列有两种：参考帧的基于Z字形扫描的排列和非参考帧的基于块测试的排列。仿真结果表明，在相同的压缩比下，峰值信噪比比比在无置换情况下可提高3-7db左右。(we propose a new scheme to compress 2D signals using parallel compressed sensing. According to this seheme, the reeonstruction at the decoder can be performed in parallel. By performing certain permutation on a 2D signal, all columns are insured to have approximately the same density level and can be sampled using the same measurement matrix. In this way, vectorization of a 2D signal can be avoided, and thus the size of the measurement matrix can be dramatically reduced. We prove that with a good permutation, we can have a tighter upper bound on reconstruction mean square error. To illustrate this scheme, we apply it to video compression and use two kinds of permutations for different frames: the zigzag-scanbased permutation for reference frames and the block-test-based permutation for non-reference frames. Simulation results show that under the same compression ratio, the peak signal-to-noise ratio can be improved by approximately 3-7 dB compared to the case without permutation.)
