基于LSB的直接4bit替换法，就是直接用秘密图像像素值的高4bit去替换载体图像像素值的低4bit。 (Direct 4bit substitution, that is, the direct use of the secret image pixel values of the high-4bit image pixel value to replace the carrier' s low 4bit.)

This Program compute the CIEDE94 color-difference between the sample between a reference with CIELab coordinates Labsample and a standard with CIELab coordinates Labstd The function works on multiple standard and sample vectors too

如果阵元间距小于半波长，则阵元间会产生耦合。如果阵元间距大于半波长，则阵列上会现多余的旁瓣，从而降低天线阵列的性能。而当阵列间距选取为半波长时，所估测出的效果最优。(If the array element spacing is less than half wavelength, it will produce coupling between array elements. If the array element spacing is greater than half wavelength, the array will now be extra sidelobes, thus reducing the performance of the antenna array. When the array spacing is half wavelength selection, the best estimate the effect.)
