Two psychophysical experiments were conducted to analyze the role of color attributes in simple tasks involving color matching and discrimination. In Experiment I observers made color matches using three different adjustment control methods. The results showed that the Lightness, Chroma, Hue (LCH) and the Lightness, redness/greenness, blueness/yellowness(More)
We apply in this paper the weak Galerkin method to the second order parabolic differential equations based on a discrete weak gradient operator. We establish both the continuous time and the discrete time weak Galerkin finite element schemes, which allow using the totally discrete functions in approximation space and the finite element partitions of(More)
The purpose of this proposal is to obtain funding for a collaborative project between members of the Munsell Color Science Laboratory (MCSL) and Digital Imaging and Remote Sensing Laboratory (DIRS) to investigate the application of color in the visualization of highdimensional remote-sensing products for interpretation and exploitation. Using a spectral(More)
