The effect of two anti-fungal treatments (metrafenone and boscalid + kresoxim-methyl) on the color and phenolic profile of Tempranillo and Graciano red wines has been studied. To evaluate possible modifications in color and phenolic composition of wines, control and wines elaborated with treated grapes under good agricultural practices were analyzed. Color was assessed by Glories and CIELab par...

This paper addresses the problem of interpolating missing color components at the output of a Bayer color filter array (CFA), a process known as demosaicking. A luma-chroma demultiplexing algorithm is presented in detail, using a least-squares design methodology for the required bandpass filters. A systematic study of objective demosaicking performance and system complexity is carried out, and ...

Color appearance models provide a powerful tool for achieving a viewing condition independent color representation. However, current color appearance models such as CIECAM97s and CAM97s2 are more complex than previous CIE device independent color spaces, such as CIELAB and CIELUV. Therefore it is important to understand how to correctly measure and set the input parameters. This paper provides ...

Human face detection plays an important role in many applications such as face recognition , human computer interface, biometrics, area of energy conservation, video surveillance and face image database management. The selection of accurate color model is the first need of the face detection. In this paper, a study on the various color models for face detection i.e. RGB, YCbCr, HSV and CIELAB a...
