Color images often must be color balanced to remove unwanted color casts. We extend previous work on using a neural network for illumination, or white-point, estimation from the case of calibrated images to that of uncalibrated images of unknown origin. The results show that the chromaticity of the ambient illumination can be estimated with an average CIE Lab error of 5∆E. Comparisons are made ...

The choice of test images is an important part of the experimental evaluation of colour reproduction algorithms. As previous studies show low levels of correlation between individual image results, this study explores the impact of test image choice on the overall results of gamut mapping algorithm evaluation experiments. A set of fifteen test images is used in an experiment designed according ...

It has been found that the L* function defined in the CIELAB color space is not suitable to predict the human visual perception of modulated patterns at high spatial frequencies. For example, in multilevel haiftoning (multitoning), when output levels are equally spaced in L , it has been observed that the visibility ofthe resulting multitone patterns is not uniform across different parts of the...

We predicted that adopting a performance-approach vs. performance-avoidance goal would lead to physiological responses characteristic of psychological states of challenge vs. threat appraisals, respectively. Furthermore, we predicted that these states would mediate the effects of goals on performance. Twenty-seven undergraduate females performed a task described as identifying either exceptiona...

Diagnosis-Related Group (DRG) systems across Europe are very heterogeneous, in particular because of different classification variables and algorithms as well as costing methodologies. But, given the challenge of increasing patient mobility within Europe, health systems are forced to incorporate a common patient classification language in order to compare and identify similar patients e.g. for ...

This study aimed to evaluate venous hemodynamic and morphological changes and associated factors in patients with Peripherally Inserted Central Catheters (PICCs), to provide evidence for rational clinical use of PICCs. Venography was performed at different time points in 87 patients with PICCs to observe hemodynamic, morphological, and structural changes. Related laboratory blood tests were als...
