本文件中代码使用前馈卷积神经网络对图像进行去噪(In this paper, we use the feedforward convolution neural network to denoise the image.)

在分析聚束合成孔径雷j盘(SAR)方位向时频关系的基础上，提出了一种新的全孔径分辨率SAR成像算法。 根据SAR在条带与聚束模式下回波信号之间的差别，利用现有成熟的条带SAR成像算法实现先对聚束SAR各方位向子 孔径成像，而后再将各方位子孔径带宽合成为全孔径带宽，以形成具有全孔径分辨率的SAR图像，极大降低了系统PRF 的要求。(In the analysis of spotlight synthetic aperture radar dish j (SAR) azimuth based on the time-frequency relationship, a new full-aperture resolution SAR imaging algorithm. According to SAR in strip and spotlight mode, the difference between the echo signal, the use of existing mature band SAR imaging algorithm first bit of the spotlight SAR the parties to the sub-aperture imaging, and then place then all the bandwidth synthetic aperture the bandwidth for the full aperture to form a full aperture resolution SAR images, greatly reducing the system PRF requirements.)

基于分块可压缩传感的图像重建，里面包括contourlet、DWT、DDWT、DCT，图像压缩传感与重建。(Based on the sub-block compressible sensing image reconstruction, which include the Contourlet DWT DDWT,, DCT image compression sensing and reconstruction.)

用matlab实验的进行均值滤波的改进函数(Experiments carried out using matlab mean filter to improve the function of)

实验中自己写的enhanceImage，myhisteq，myimhist，并附有详细的文档，可正常运行并详细测试过。(Experiment to write their own enhanceImage myhisteq, myimhist, with detailed documentation, can be normal operation and tested in detail.)

encryption and decryption of image using bit XOR..

自写的一种基于局部对比增强的GVFsnake图像分割方法，参考了xu的gvf，但本方法分割效果更好。(Since the writing of a local contrast enhancement based on image segmentation method of GVFsnake reference xu the gvf, but this method is better segmentation.)

2014年西安电子科技大学数字图像处理上机实验，同时是研究生和本科生的代码及作业 (2014 Xi' an University of Electronic Science and Technology of digital image processing experiments on board, while the graduate and undergraduate students and job code)
