Linear transforms are widely used in signal compression. They have the primary objective of concentrating the signal energy on a few coefficients, thus preparing the data for the subsequent ...

Discrete transform techniques form the mathematical foundation of modern image and video compression by converting spatial or temporal pixel data into spectral coefficients that reveal salient ...

In recent years, quantum image computing draws a lot of attention due to storing and processing image data faster compared to classical computers. A number of approaches have been proposed to ...
