求取信号的峰值点。可以通过设置信号峰值范围、信号幅度来确定特定的峰值点。(The peak point of the signal to strike. Can set the scope of the signal peak, the signal range to determine the specific point of the peak.)

由地震剖面图像格式生成segy地震数据的M程序。matlab语言写的，非常好用。 包含示例。 (By the seismic profile image format to generate seismic data segy the M procedure. matlab language, very easy to use. Contains the sample.)

实现通过用户给定B样条曲线的控制顶点、设定B样条曲线的次数及类型，进而绘制出相应的B样条曲线和对应的基函数图形。并且可以通过鼠标拖拽控制顶点修改B样条曲线和对应的基函数图形。从而，对B样条曲线和基函数的性质有更深入更直观的了解，理解B样条曲线和基函数的对应关系，在以后的学习中能更好地运用B样条曲线。(The number and type of user to achieve a given control vertices B-spline curve, set the B-spline curves, and then draw the corresponding B-spline basis functions and the corresponding graphic. And can be modified by dragging the mouse to control the apex B-spline curves and the corresponding basis function graphics. Thus, the nature of the B-spline curves and basis functions have a deeper and more intuitive understanding, understanding of the correspondence between the B-spline curves and basis functions in later learning to better use of B-spline curves.)

这是关于图像区域生长的源码，希望对这方面的人有所帮助(This is on the source image region growing, I hope people in this area help)

在数字图像处理中，灰度直方图是最简单且最有用的工具，可以说，对图像的分析与观察直到形成一个有效的处理方法，都离不开直方图。(in digital image processing, the histogram is the simplest and most useful tool, it can be said that the right image analysis and observation until the formation of an effective treatment method has been based on histogram.)
