read_ENVIimagefile
说明: ENVI软件标准格式的高光谱遥感图像含有两部分:一个是高光谱图像 '*.img ',另一个是遥感图像头文件 '*.hdr',该文件记录了遥感图像的信息,如图像尺寸、波段数、数据类型和大小端等。如果缺少头文件,将无法对遥感图像进行读取,因此头文件十分重要。
在Matlab中,将利用函数multibandread()对多波段(高光谱/多光谱)图像进行读取。(The hyperspectral remote sensing images of ENVI software standard format contain two parts: one is hyperspectral image'*.img ', the other is the remote sensing image header file'*.hdr', which records the information of remote sensing image, such as image size, band number, data type and size end, etc. If there is no header file, it will not be able to read remote sensing images, so header files are very important.
In Matlab, multibandread () is used to read multiband (hyperspectral / multispectral) images.)

三次B样条曲线拟合算法
B样条曲线分为近似拟合和插值拟合,所谓近似拟合就是不过特征点,而插值拟合就是通过特征点,但是插值拟合需要经过反算得到控制点再拟合出过特征点的B样条曲线方程。这里会一次介绍两种拟合算法。
