The effect of illumination cues on color constancy in simultaneous identification of illumination and reflectance changes

Lari S. Virtanen, Maria Olkkonen, Toni Saarela

This study investigates how illumination and reflectance changes are perceived and identifies that their judgments are not independent, with visual cues improving color constancy.

Visual discrimination of optical material properties: a large-scale study

Masataka Sawayama, Yoshinori Dobashi, Makoto Okabe, Kenchi Hosokawa, Takuya Koumura, Toni Saarela, Maria Olkkonen, Shin’ya Nishida

This study constructs a database of material images with annotated visual discrimination performance and shows that material discrimination depends on illumination and geometry, with individual differences in glossiness perception.
