全向阵元和有向阵元的模式空间图，有助力于理解宽带波束形成(the mode pattern of ominidirectional array elements and directional array, it is helpful to understand the broadband beamforming)

matlab图形图像处理函数，包括所有有关matlab图形图像的函数(matlab graphic image processing functions, including all the graphic image of the function matlab)

说明：  压缩包内含有VC++中调用Matlab .m函数编译后的动态链接库和VC++中调用Matlab .m函数编译后的对应c函数(Compressed packets contain VC++ Calling Matlab. M function compiled dynamic link library and VC++ Calling Matlab. M function compiled function corresponds to c)

根据)EF 特性中的对比度敏感度， 即空间频率特性曲线，对图像进行二维多级小波分解，由分解后的各小波分量，提取各频段相应的亮 度、清晰度和相关度指标；然后将这三个指标的几何平均与频段加权系数的内积做算术平均，以此作 为图像质量的综合评价指标(According to) EF characteristic of contrast sensitivity, that is spatial frequency characteristic curve, the image is two-dimensional multi-level wavelet decomposition, the decomposition of the wavelet component, extract the frequency band corresponding brightness, clarity and relevance of indicators then the geometric mean of these three indices and the band doing weighted coefficient of the arithmetic mean within the product as a comprehensive evaluation of image quality index)
