Simultaneous contrast and gamut relativity in achromatic color perception
Simultaneous contrast refers to the respective whitening or blackening of physically identical image regions surrounded by regions of low or high luminance, respectively. A common method of measuring the strength of this effect is achromatic color matching, in which subjects adjust the luminance of a target region to achieve an achromatic color match with another region. Here I present psychoph...
متن کاملLighting Condition Adaptation for Perceived Age Estimation
Over the recent years, a great deal of effort has been made to age estimation from face images. It has been reported that age can be accurately estimated under controlled environment such as frontal faces, no expression, and static lighting conditions. However, it is not straightforward to achieve the same accuracy level in real-world environment because of considerable variations in camera set...
متن کاملPreferred Color Gamut Boundaries for Wide-Gamut and Multi-Primary Displays
Preferred chroma enhancement and its dependence on hue are studied in a twopart experiment using a wide-gamut multi-primary display. Earlier research showed a clear dependence on hue but was limited by the gamut of the display it employed; the present work builds on this while removing the gamut constraints. In the first part of the present experiment, a tuning task was used to refine the prefe...
متن کاملPerceptually-based Gamut Extension Algorithm for Emerging Wide Color Gamut Display and Projection Technologies
While wide color gamut (WCG) capabilities are a key element of emerging display and projection technologies, at present most image content is recorded using standards such as DCI-P3 for cinema or BT.709 for TV that have a reduced color gamut. Therefore, there is a need for gamut extension methods that process regular content and allow to appreciate the full color potential of new displays, impr...
متن کاملGeneral-Purpose Gamut-Mapping Algorithms: Evaluation of Contrast-Preserving Rescaling Functions for Color Gamut Mapping
Experiments were performed to test a set of general-purpose gamut-mapping functions. These gamut-mapping algorithms utilized contrast-preserving scaling functions. These algorithms were tested against the GCUSP gamut-mapping algorithm proposed by Morovic and Luo, which was shown to have very good "universal" gamut-mapping characteristics. The results of these experiments showed that vast improv...
