说明： 我们描述了所提出的方法对超声（US）信号的压缩多路复用的直接应用。该技术利用压缩多路复用器架构进行信号压缩，并依靠频域中US信号的联合稀疏性进行信号重建。由于换能器元件具有压电特性，因此可以获得有关US信号频率支持的准确先验知识，并且可以在联合稀疏算法中使用。
我们在数值实验中验证了所提出的方法，并显示了它们在秩次缺陷情况下相对于最新方法的优越性。我们还证明，与没有已知支持的重建相比，该技术可显着提高体内颈动脉图像的图像质量。(We describe a direct application of the proposed methods for compressive multiplexing of ultrasound (US) signals. The technique exploits the compressive multiplexer architecture for signal compression and relies on joint-sparsity of US signals in the frequency domain for signal reconstruction. Due to piezo-electric properties of transducer elements, accurate prior knowledge of the frequency support of US signals is available and can be used in joint-sparse algorithms.
We validate the proposed methods on numerical experiments and show their superiority against state-of-the-art approaches in rank-defective cases. We also demonstrate that the techniques lead to a significant increase of the image quality on in vivo carotid images compared to reconstruction without known support.)

SAR雷达图像点目标仿真(RD算法和CS算法)
合成孔径技术实现雷达成像。合成孔径雷达(Synthetic Aperture Radar ，简称 SAR)是一种高分辨率成像雷达技术。它利用脉冲压缩技术获得高的距离向分辨率，利用合成孔径原理获得高的方位向分辨率，从而获得大面积高分辨率雷达图像。(Synthetic aperture technique for radar imaging. Synthetic Aperture Radar is a kind of high-resolution imaging radar technology. It uses pulse compression technology to obtain high range resolution and synthetic aperture principle to obtain high azimuth resolution, so as to obtain large area high resolution radar image.)

对海量图像进行分块索引，可以不限数据量大小对图像进行漫游。
使用办法，首先选择图像处理中导出索引这一功能，将海量的BMP图像格式转换为自定义的img格式，再在打开菜单中打开IMG格式的影像，就可以完成对海量数据的浏览，数据量不受内存限制，只受硬盘大小限制，另外该软件还包括其他一些图像格式之间的转换，主要用在GIS领域-Images of the mass block index, you can open the volume of data roaming size image. Use practices, the first choice of image processing to export the index of this function, will be massive conversion of the BMP image format for custom img format, and then open the menu opens in IMG format images, you can complete the huge amount of data browsing, data not subject to memory limitations, only by hard drive size limit, while the software also includes a number of other conversion between image formats, mainly used in the field of GIS
