Colorimetric reproduction requires calibrated color output devices. One way to characterize a color output device is with a three-dimensional look-up table which maps the tristimulus values, t, to the control values, c of the output device. The functional form of the output device can be written in vector notation as t = F(c). The purpose of calibration is to define an inverse mapping from tris...

A method for visualizing high dimensional medical image data is proposed. The method operates on images in which each pixel contains a high dimensional vector, e.g. a time activity curve (TAC) in a dynamic positron emission tomography (dPET) image, or a tensor, as is the case in diffusion tensor magnetic resonance images (DTMRI). A nonlinear mapping reduces the dimensionality of the data to ach...

We propose to use a hybrid downconverter system comprising low-cost green perovskite-polymer composite films for liquid crystal display (LCD) backlight unit (BLU) to realize wide color gamut. Recently, ultrastable, highly luminescent CH3NH3PbBr3 (MAPbBr3) organic-inorganic perovskite-polymer composite films have been developed. These films exhibit outstanding color quality with a full-width-at-...

Gamut boundary determination is an important step in device characterisation and colour gamut mapping. Many different algorithms for the determination of colour gamuts are proposed in the literature. They vary in accuracy, computational efficiency, and complexity of the resulting triangulated gamut surface. Recently, an algorithm called uniform segment visualization (USV) was developed. The gam...

Two criteria for selecting ink sets for six-color lithographic printing are discussed. The first is the volume, in CIELAB space, of an approximation of the gamut. The second is the number of pixels within a digital image (or images) whose colors are contained within the approximate gamut. In order to obtain a balance between accuracy and efficiency, the different steps in the process are priori...
