In a raw photographic image, the observed colors are a mixture of material reflectance and colored illumination. For further processing, the color influence of the light source is often considered a disturbance. In such cases, it is desireable to neutralize the color of the light source, often referred to as white balancing. Successful white balancing often requires an estimate of the color of ...

Our recent results show the efficacy of pain suppression by exposure of antinociceptive acupuncture points (APs) to white polarized (P) light. But it is known that white light contains electromagnetic waves of different length (colors) and, possibly, not all of them produce a similar effect. There are no comparative data about analgesic affects of the different colors of P light now. The purpos...

Many recent systems for computer artwork generation with evolutionary algorithms have been interactive, relegating the task of evaluating new genotypes to their users. In contrast, we are interested in fully automating the entire evolutionary cycle applied to art work generation. We set out to produce a program that would generate artwork in the style of the Dutch painter Piet Mondrian, who was...

Micro X-ray fluorescence (μ-XRF) possesses a powerful analytical technique able to detect macro- and micro-elements. Each plant variety has unique elemental composition important role in the germination process. The aims of this study were (1) map elements quantities soybean seed coat endosperm, (2) investigate how various might mediate inter-relationship or correlation between within genotypes...

In this study, the effects of the color of different post-core materials and different colored cements on the color and esthetic of all-ceramic restorations were investigated. Three groups of post-cores (ceramic, Cr-Ni and Cr-Ni + opaque), one sample per each group, were prepared as discs 14 ± 0.05 mm in diameter and 1.5 ± 0.05 mm in thickness. A total of 40 cement samples, 10 per each group (o...

BACKGROUND Bright- or light-colored vehicles are sometimes regarded as safer because they are presumably more visible. We examined the effect of vehicle color on the risk of being passively involved in a collision. METHODS This paired case-control study used data from the Spanish database of traffic crashes. We selected those collisions from 1993 to 1999 in which only one of the drivers commi...

in order to determine resistance genetically potential of some bean genotypes to bean common mosaic virus, two separated experiments in randomized complete block design with 25 genotypes and three replications was conducted in iau shiraz branch. the first experiment and the second one were performed in normal and bcmv infected conditions, respectively. plants were inoculated in cotyledon leaf a...

We previously presented a single-channel speech enhancement technique called the Modified Phase Opponency (MPO) model. The MPO model is based on a neural model called the Phase Opponency (PO) model. The efficacy of the MPO model was demonstrated on speech signals corrupted by additive white noise. In the present work, we extend the MPO model to perform efficiently on speech signals corrupted by...
