A Psychological Study: Importance of Contrast and Luminance in Color to Grayscale Mapping

no code implementations7 Feb 2024 Prasoon Ambalathankandy, Yafei Ou, Sae Kaneko, Masayuki Ikebe

While preserving contrast is important for maintaining visual quality, other factors such as preserving information relevant to the specific application or task at hand may be more critical for achieving optimal performance.

A Sub-pixel Accurate Quantification of Joint Space Narrowing Progression in Rheumatoid Arthritis

no code implementations19 May 2022 Yafei Ou, Prasoon Ambalathankandy, Ryunosuke Furuya, Seiya Kawada, Tianyu Zeng, Yujie An, Tamotsu Kamishima, Kenichi Tamura, Masayuki Ikebe

With its sub-pixel accuracy far beyond manual measurement, we are optimistic that our work is promising for automatically quantifying JSN progression.

A color temperature-based high-speed decolorization: an empirical approach for tone mapping applications

no code implementations31 Aug 2021 Prasoon Ambalathankandy, Yafei Ou, Masayuki Ikebe

This phenomena creates a perception of warm colors "advancing" toward the eye, while the cool colors to be "receding" away.
