Description: 针对目前流行的一种文件格式segy 处理的软件包，- Since the original SEG Y Data Exchange Format [revision 0, reference page 45] was published in 1975 it has achieved widespread usage within the geophysical industry. This widespread usage has brought about many proprietary variations. Since the publication of SEG Y rev 0, the nature of seismic data acquisition, processing and seismic hardware has changed significantly. The introduction of 3-D acquisition techniques and high speed, high capacity recording media dictate the need for revisions to the SEG Y rev 0 format. The major changes introduced by SEG Y rev 1 are: standardizing the location of header information needed for current processing practices and defining a SEG Y data set as a byte stream format. The SEG Technical Standards Committee strongly encourages producers and users of SEG Y data sets to move to the revised standard in an expeditious fashion.

Description: 提出了一种基于非下采样 Contourlet变换 ( NSCT)和马尔科夫随机场 (MRF)相结合的纹理图像分割算法。算法包括两
个步骤, 首先通过 NSCT实现对图像纹理特征的提取, 并使用模糊 C-均值完成对图像的初始分割 然后将初始分割结果用 MRF模型
表示, 通过贝叶斯置信传播得到图像的最终分割结果。实验结果表明, 对于纹理图像,该方法在分割错误率、 区域一致性以及边缘的
准确性方面都比传统小波变换的方法有了明显的改善。-A tex ture i m age seg m entation a l go rithm based on comb i nati on of non-down sa m pling Contourlet transfor m ( NSCT) andM arkov

Description: segy指的是“segy格式地震数据”。
地震数据一般以地震道（trace）为单位进行组织，采用SEG-Y文件格式存储。SEG-Y格式是由SEG （Society of Exploration Geophysicists 地球物理学者协会）提出的标准磁带数据格式之一，它是石油勘探行业地震数据的最为普遍的格式之一。处理地震记录文件形式：
（1） 原始采集记录文件：
*.dat
*.SG2 （SEG-2 记录格式或CSP记录格式）
（2） 处理数据记录文件：
*.d（解编后的地震记录格式）
*.sgy 非标准SEG-Y 记录格式（无卷头）。
注： * 代表文件名，由小于或等于20个数字或字符组成。(segy refers to "segy format seismic data."
Seismic data is typically organized in trace units and stored in the SEG-Y file format. The SEG-Y format is one of the standard tape data formats proposed by the Society of Exploration Geophysicists (SEG) and is one of the most popular formats for seismic data in the petroleum exploration industry. Processing of seismic record file format:
(1) the original acquisition record file:
* .dat
* .SG2 (SEG-2 recording format or CSP recording format)
(2) Processing data record file:
* .d (Decoded Seismic Recording Format)
* .sgy Non-standard SEG-Y recording format (without header).
Note: * Representative file name, composed of less than or equal to 20 numbers or characters.)
