Genotypes, phenotypes and pedigrees of 6 breeds of dairy sheep (including subdivisions of Latxa, Manech, and Basco-Béarnaise) from the Spain and France Western Pyrenees were used to estimate genetic relationships across breeds (together with genotypes from the Lacaune dairy sheep) and to verify by forward cross-validation single-breed or multiple-breed(More)
Digital image capture devices cannot be used directly as instruments for color measurement. The main stages for characterizing a digital image capture device as an instrument for color measurement are the spectral and spatial characterization and the color transformation from the RGB device dependent space to a device independent space such as CIE-XYZ. We(More)

In order to improve the precision of colorimeters based on a digital image capture device, we increased the number of acquisition channels by using a supplementary filter placed in front of the color camera and taking two images of the scene: one without the filter (3 RGB channels) and one with the filter (3 different UVW channels). We selected a wide-band(More)
Digital image capture devices cannot be used directly as instruments for color measurements because the RGB digital data are not XYZ tristimulus values. The main stages to characterize a digital image capture device as an instrument for color measurements are the spectral and spatial characterization and the color transformation from the RGB device(More)
