A Bayesian computational model is described, which is able to account for the acquisition of the meanings of basic colour terms by children learning their first language. Examples of colours named by particular colour terms are stored in a conceptual colour space, and Bayesian inference is used to determine the extent of the extension of each colour term based upon these examples. This method c...

The presence of lignin and its degraded products such as tannin and humic acids is the main reason causing the aerobically-treated palm oil mill effluent (AT-POME) to display colour at the point of discharge. In this work, a hybrid method is developed to treat the AT-POME sample that was conventionally treated by biological method. This hybrid method combines coagulation and nanofiltration (NF)...

Skin colour detection is frequently been used for searching people, face detection, pornographic filtering and hand tracking. The presence of skin or non-skin in digital image can be determined by manipulating pixels’ colour and/or pixels’ texture. The main problem in skin colour detection is to represent the skin colour distribution model that is invariant or least sensitive to changes in illu...

We address the joint segmentation of regions around faces into different classes — skin, hair, clothing and background — and the learning of their respective colour models. To this end, we adopt a Bayesian framework with two main elements. First, the modelling and learning of prior beliefs over class colour distributions of different kinds, viz. discrete distributions for background and clothin...

the objective of this study was to investigate dehydration kinetics of barberry (berberis vulgaris l.) at different drying temperatures (60 ºc, 70 ºc, 80 ºc), air velocities (0.3 m s-1, 0.5 m s-1, 1 m s-1) with two types of pretreatment. drying time and colour quality during dehydration were experimentally determined. barberries were dried from the initial moisture content of 73.44% (w.b.) to t...

Figure 1. Visual comparison of equidistant model parallel (colour dashed) lines overlayed on all the image (bold colour and black) lines: (a) our work, (b) baseline, (c) our work optimized, and (d) baseline optimized, when fitted using three image lines (black lines). Figure 3. Equidistant model parallel (Red and Green colour) lines overlayed on the perspectively distorted checkerboard grid ima...

In the colour coded environment of the RoboCup 4 Legged League it is crucial to extract as much colour information as possible from an image without error. To do this requires hours of manual YUV pixel mapping and testing to ensure robustness under all possible lighting conditions. The YUV colour space is a very convenient standard for transmission of video data, but for colour classification a...

Colour Image segmentation is one of the prime requisites for computer vision and analysis. Much work has been reported in literature regarding colour image segmentation under HSI colour space and Gaussian mixture model (GMM). Since the Hue and Saturation values of the pixel in the image are non-negative. And may not be meso-kurtic, it is needed left truncate the Gaussian variate and is used to ...
