About me

 Kyong Hwan, Jin

I'm an enthusiastic researcher on imaging science - always curious on imaging principles and background theory.  In image processing, my research domain ranges from designing algorithm to implementing software. Recent interests are image quality enhancement and real inverse problems from computational photography using learnable non-linear systems, a.k.a, deep neural networks. I believe that our research trials make a step toward the better human life.
