In the field of display technology, panels are mainly composed pixels three primary colors red, green and blue, which have basically same spectra in production batch due to consistency process. Thus, using commercially available color cameras measure coordinates is possible. However, actually different or even areas panel slightly different, will lead a certain error principle. this paper, we a...

In neon color spreading displays, both a color illusion and perceptual transparency can be seen. In this study, we investigated the color conditions for the perception of transparency in such displays. It was found that the data are very well accounted for by a generalization of Metelli's (1970) episcotister model of balanced perceptual transparency to tristimulus values. This additive model co...

This paper presents a neural network approach to image color quantization and hence image data compression. Self-organizing feature maps form a basis for general vector quantization and this is applied to the tristimulus color values of image pixels. For image telecommunication systems such as videoconferencing, it Is desirable to constrain the encoder to a single pass of the image using the no...

Tristimulus values (X, Y, Z) and CIELAB colourimetric coordinates have been measured in m. Longissimus dorsi and m. Triceps braquialis caput longum muscles in 86 light carcasses of lambs from different origins. By applying to these data different mathematical methods (ANOVA, Discriminant Analysis, Principal Components Analysis and Cluster Analysis) we have obtained a good classification of thes...

The RGB signals generated by different cameras are not equal for the same scene. Therefore, cameras are characterized based on a CIE standard colorimetric observer. One method of deriving a colorimetric characterization matrix between camera RGB output signals and CIE XYZ tristimulus values is least squares polynomial modeling. Yet, this involves tedious experiments to obtain a camera transfer ...

An essential objective of Precision Livestock Farming (PLF) is to use sensors that monitor bio-responses contain important information on the health, well-being and productivity farmed animals. In literature, vocalisations animals have been shown can enable farmers improve their animal husbandry practices. this study, we focus vocalisation birds specifically develop a sound recognition techniqu...

A retrospective evaluation of attitudinal, behavioural and knowledge change among diverse stakeholder groups was conducted in Limpopo Province of South Africa to assess the effectiveness of a series of values clarification (VC) interventions. Telephone and face-to-face interview (193) results revealed that over two-thirds (70.2%) reported behavioural changes and 93.2% reported increased compass...
