Quantum image processing: the pros and cons of the techniques for the internal representation of the image. A reply to: A comment on "Quantum image processing?"

This work demonstrates the practical infeasibility in the implementation of the techniques known as flexible representation of quantum images (and its variants) and novel enhanced quantum representation of digital images (and its variants). Besides, the implementation of the technique known as quantum Boolean image processing has proven to be extremely successful on: (a) the four main quantum simulators on the cloud, (b) two physical quantum computers, and (c) three optical tables where it also demonstrated: its resource economy and its great robustness (immunity to noise), among other advantages, in fact, without any exceptions.
