The relationship was derived for computer‐controlled color CRT displays between spectral radiant exitance emitted and digital counts. The derivation was historical and could be traced to pioneering work in photographic sensitometry, vacuum tube physics, and broadcast television. By performing...
The colorimetric characterization of computer‐controlled CRT displays require radiometric measurements with high precision and accuracy in order to achieve acceptable colorimetric accuracy in defining stimuli generated with this type of imaging modality. Precision and accuracy requirements for...
The study was made for structure of categorized color space in the aperture and the surface color modes. The color appearances of two modes were reproduced on a CRT display with or without a surround configuration. Subjects made categorical color naming with 11 basic color terms. The (x,y,L)...
One problem with the use of computer graphics monitors in vision experiments is spatial inhomogeneity: phosphor output intensity can vary between screen locations. This feature complicates accurate display of stimuli—either output must be confined to a small portion of the screen or variability...
A fast and accurate algorithm for computing color gamuts has been developed. In the form presented here for illustration, color gamuts are computed from the dye amounts of subtractive color mixtures. Based on the one‐to‐one correspondence between dye amount space and color space, the simple...
This work attempts to determine the best index for measuring the whiteness of human teeth. For this the classifications obtained from various whiteness indices have been compared, using Spearman's correlation coefficient, with the responses of 20 observers judging a group of 20 samples of...
