The other two transformations are the transformation of power method, which includes n power sources and N power roots. These transformations can be given by the expression: S = CR ^ γ, the symbol of γ is called γ, so this transformation is also called gamma transformation. The change of gamma value can enhance the image. Different displays have their own gamma correction, which is why they display their image at different intensities. This type of conversion is used for image enhancement techniques for different types of display devices. The gamma of different display devices is different. For example, the CRT gamma is between 1.8 and 2.5, which means that the image displayed on the CRT is black. Coded by omoniwa babatunji
