In this paper we present an alternative way to compute the coefficients of a characteristic polynomial matrix via trace, determinant and sum minors that may be useful in determining local stability conditions for mappings.

A psychophysical evaluation was performed to test the quality of several color gamut mapping algorithms. The task was to determine which mapping strategy produced the best matches to the original image. Observer preference was not considered. The algorithms consisted of both devicedependent and image-dependent mappings. Three types of lightness scaling functions (linear compression, chroma weig...

S As graphics hardware is available on most PCs these days, hardware-assisted real-time rendering becomes more important in many applications, such as games or virtual reality. Texture mapping is also important in graphics rendering, because it gives much visual detail without modeling of complex geometry. Conventional texture mapping by graphics hardware relies on the linear interpolations of ...
