DOI: 10.1007/s10043-017-0320-4
Abstract: The color appearance of a food image is very important for making it look delicious. Many food images acquired in low illumination environments do not give delicious impressions because of the deterioration of their color… read more here.

DOI: 10.1177/0301006619847590
Abstract: The human visual system can extract information on surface reflectance (lightness) from light intensity; this, however, confounds information on reflectance and illumination. We hypothesized that the visual system, to solve this lightness problem, utilizes the… read more here.

DOI: 10.1177/2041669518761731
Abstract: The purpose of the present study is to propose a simple algorithm for color appearance simulation under a color illuminant. Achromatic point is a chromaticity of rays that appear neither red nor green, neither blue… read more here.

DOI: 10.1515/intag-2016-0086
Abstract: Abstract Investigations were performed to study the freeze-drying process of kale (Brassica oleracea L. var acephala). The process of freeze-drying was performed at temperatures of 20, 40, and 60°C for whole pieces of leaves and… read more here.
