合成孔径雷达点目标成像RD算法，模型参考合成孔径雷达成像算法与实现(Synthetic aperture radar point target imaging algorithm RD, model reference synthetic aperture radar imaging algorithm and implementation)

Multiclass Spectral Clustering Algorithm，和Dominant-set算法同属于较常用的聚类算法，用于图像分割等(Multiclass Spectral Clustering Algorith m, and Dominant-set algorithm is more commonly used with the clustering algorithm for image segmentation, etc.)

用matlab实现两幅彩色图像的无缝融合，输出结果为灰度图象(Using two color images matlab realize seamless integration, the output for gray-scale image)

matlab区域增长图像分割程序，通过种子点搜索邻域的方法进行增长(matlab image segmentation procedures for regional growth)

说明：  对图像进行中值金字塔分解后，分别求取各层的概率密度函数(Image after median pyramid decomposition, respectively, to strike all floors of the probability density function)

图着色问题（Graph Coloring Problem, GCP）又称着色问题，是最著名的NP-完全问题之一。路线着色问题是图论中最著名的猜想之一。(Graph coloring problem (Graph Coloring Problem, GCP), also known as coloring problem, is the most famous NP-complete problems. Line graph coloring problem is one of the most famous conjecture.)

双峰法是一种简单的阈值分割方法，即如果灰度级直方图呈现明显的双峰状，则选双峰之间的谷底所对应的灰度级作为阈值分割。(Two peaks is a simple threshold segmentation method, that is, if the gray level histogram showed a clear bimodal shape, then choose between the two peaks corresponding to the bottom of the gray level as threshold segmentation.)

根据paper思想，自己编写的SPIHT编解码。可以处理不同图像大小的小波系数，严格按照paper中的算法编写。细节见说明文档(under the paper thinking, their preparation SPIHT codec. Image can handle different sizes of the wavelet coefficients and strictly according to the paper prepared algorithm. For details, see the documentation)

对图像进行处理，利用拉普拉斯锐化进行边缘检测。(The image is processed and the edge is detected by Laplasse sharpening.)

SEISPLOT 可以弥补FIMAGE软件带来的不足，即可以实时地显示更多剖面。而且还可以进行其它格式的转换。(seisplot is a software for seismic profile viewing.)
