Forgers beware: math cracks fakes

Astronomers will gaze with greater clarity at the stars, thanks to CUHK professor Raymond Chan Hon-fu – and art forgers should be careful.


An algorithm developed by Professor Chan is the fastest way of solving Toeplitz systems, a form complex linear equations. By breaking down image and signal processing into mathematical terms, he has been able to design computer algorithms that can dramatically increase the image quality of telescopes or the verification of van Gogh paintings.
