提出了一种基于 JPEG/JPEG2000相结合的医学图像感兴趣区域压缩方法。该方法对在人为选定 医学图像的感兴趣区域采用无损的 JPEG2000压缩 ,而对其他图像区域则采用高压缩比的 JPEG压缩,较好地解决了医学图像的高压缩比和高质量之间的矛盾。(Based on a combination of JPEG/JPEG2000 region of interest of medical image compression method. The method of artificially selected region of interest of medical images using lossless JPEG2000 compression, and on other image regions using high compression ratio of JPEG compression, a better solution to the medical image and high-quality high-compression ratio between the contradictions.)

程序模拟的是潜水艇这类大的铁磁性材料穿过海域对电磁场（地磁场）带来的变化以及如何通过物理手段消除这种变化(Program to simulate the submarine through the ferromagnetic material of such a large area of electromagnetic fields (magnetic field), and how the changes brought about this change through physical means to eliminate)

digital modulation techniques

说明：  用于图像处理和信号DOA估计，是基于块稀疏的正交匹配追踪算法(This is an algorithm based on signal block sparsity, which can be used in image processing and signal DOA estimation)

基于四叉树分解并且使用区域分离和合并的图像分割(based quadtree decomposition and the use of regional separation and integration of image segmentation)

该算法，解决了不收敛的问题，聚类效果非常好。改进的蚁群算法是基于遗传算法的改进，在基本遗传算法的基础之上，加入了变异因子，产生变异，从而更快的收敛。(The algorithm solves the problem of convergence, and the clustering effect is very good. The improved ant colony algorithm is based on the improvement of genetic algorithm. On the basis of the basic genetic algorithm, the variance factor is added to produce the variation, and the convergence is faster.)

一种智能优化算法-带交叉因子的粒子群优化算法(With cross factor particle swarm)

语音信号的iir滤波器设计,从带有噪音的信号中提取原始声音.目前，MP3播放器一般功率放大器的工作频率范围就是这个范围。但是大部分有用的和可理解的信息的频率在200到3500Hz之间。所以我们可以在这个范围间滤波，达到使声音可理解的要求。现将数字滤波器的设计指标设为通带截止频率fb=600HZ,阻带频率fc=1200HZ,通带波纹Ap=1dB，阻带波纹As=40dB,要求确定H(z)。(design of the iir filter, get the original voice without noise)
