  Quantum Image Processing (QIP)is an exciting new field showing a lot of
promise as a powerful addition to the arsenal of Image Processing techniques.
Representing image pixel by pixel using classical information requires an
enormous amount of computational resources. Hence, exploring methods to
represent images in a different paradigm of information is important. In this
work, we study the representation of images in Quantum Information. The main
motivation for this pursuit is the ability of storing N bits of classical
information in only log(2N) quantum bits (qubits). The promising first step was
the exponentially efficient implementation of the Fourier transform in quantum
computers as compared to Fast Fourier Transform in classical computers. In
addition, images encoded in quantum information could obey unique quantum
properties like superposition or entanglement.
