Short Biography

Oguzhan Ulucan is a Ph.D. student and research assistant in the department of Computer Science. In his Ph.D. thesis, he focuses on color illusion perception and computational color constancy. His research interests include image formation, intrinsic image decomposition, and machine learning. He holds a bachelor's degree (with honors) and a master's degree in electrical and electronics engineering from the Izmir University of Economics in Turkey.


2023: I have been accepted to ICVS Summer School 2023! Looking foward to it! 

2023: Two papers are accepted at IMPROVE 2023 for oral presentation!  

  • Both papers are nominated for the best student paper award!

2023: "Block-based Color Constancy: The Deviation of Salient Pixels" is accepted at IEEE ICASSP 2023!

2022: "BIO-CC: Biologically Inspired Color Constancy" is accepted at BMVC 2022!

  • Our algorithm not only mimics our sensation on color illusions but also performs color constancy! 

2022: Two papers are accepted at IEEE ICIP 2022!

Color Assimilation Illusions

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

You can find the color assimilation illusions that I created on this part of the page. If you are interested in the color illusions that I created and if you want to use them in your work, feel free to contact me. 

Here are some examples of the color assimilation illusions which I designed. In this 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.
