Short Biography

Oguzhan Ulucan is a Ph.D. candidate and a research assistant at the University of Greifswald, Germany. He received his B.Sc. (with honors) and M.Sc. degree in electrical and electronics engineering from the Izmir University of Economics, Turkey, in 2017 and 2020, respectively. Under the supervision of Prof. Dr. Marc Ebner, he is doing research on computational color constancy and color illusion perception. In his thesis, he is developing algorithms that mimic the behavior of the human visual system on both color constancy and color illusion perception. His research interests also include intrinsic image decomposition, image fusion, and machine learning.

Color Assimilation Illusion

I am interested in color assimilation illusions which I believe have a significant relationship with color constancy. 

Here are some examples of the color assimilation illusions I designed. In these illusions, the colors of the target regions are the same, i.e. triangles of the last image, we perceive them as if they are different due to their local neighbors. If you are interested in them and if you want to use them in your work, feel free to contact me.
