图片不规则变形源码，例程程序根据图片的计算，使用画板使图片不规则变形。(Pictures irregular deformation source , routine procedures according to the calculation of the picture, using the drawing board to make the image irregular deformation.)

说明：  这是用c语言实现的图形的几何变换算法，里面有许多小的功能(This is achieved using c language graphics geometric transformation algorithms, there are many small function)

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.)

说明：  其可以直接绘制vaspkit生成的能带图，直接调用即可，可以批量生成能带图(It can directly draw the band diagram generated by vaspkit)

图像几何变换（缩放、旋转）中的插值算法 ( The picture geometry transformation (缂╂斁, revolves) the center interpolation algorithm )

用于判断高光谱图像多个波段之间的相关性系数(Hyperspectral images to determine the correlation between multiple-band coefficient)

标注节点距离，批量标注节点距离。节省画图时间 提高画图效率(Marking Node Distance)

显示JPEG图片的源码.........................................(show jpeg picture)

一种用三维重建的matlab代码，有实验结果图(A three-dimensional reconstruction of the matlab code, with experimental results)

对图像进行特征提取，求均值和方差来计算提取特征。(For image feature extraction, mean and variance to calculate the extracted features.)
