1. A method comprising: receiving input image information; using a processor device for determining enhancement information based on frequency characteristics and feature information of the input image information, wherein determining enhancement information comprises performing a frequency lifting process on transform coefficients based on determined distances for lifting one or more frequency components to a higher frequency location in a transform spectrum; and mixing the enhancement information with the input image information to generate an enhanced image, wherein edge information and texture information of the input image are used for adjusting the frequency lifting process.
