The 'colour-shading effect' describes the phenomenon whereby chromatic variations affect the magnitude of perceived shape-from-shading in luminance patterns. A previous study showed that in mixed colour-plus-luminance sine-wave plaids, impressions of depth in the luminance component were enhanced by non-aligned chromatic components, and suppressed by aligned chromatic components [Nature Neurosc...

Relation extraction is the task of recognizing semantic relations among entities. Given a particular sentence supervised approaches to Relation Extraction employed feature or kernel functions which usually have a single sentence in their scope. The overall aim of this paper is to propose methods for using knowledge and resources that are external to the target sentence, as a way to improve rela...

Rotundone is a key aromatic compound for cool-climate Shiraz. This compound is produced in the skin of grape berries and extracted into wine during fermentation. This project investigated the influence of fermentation techniques on the concentration of rotundone in the resultant wine. Wine was fortified with ethanol and sucrose on the 1st and 5th days of fermentation and rotundone, volatile aro...

This work focuses on the automatic monitoring of the natural environment using images of animals. An unsupervised 3D colour texture segmentation and recognition algorithm is developed and applied in the recognition of natural patterns (monkeys) in outdoor image scenes (Amazon Forest). We present an unsupervised segmentation algorithm, which uses 3D Graph-theoretical clustering for colour images...

A ripe strawberry looks red to our eyes in sunlight and in the green light of a forest, although the spectrum of light reflected from its surface differs dramatically. This is caused by two effects: colour constancy and our ability to learn relative colour cues - the ripe strawberry remains relatively 'redder' than an unripe green strawberry. While colour constancy - the ability to recognize co...

In this paper, based on the idea of fractal key frame algorithm and by giving the colour correspondence principle of contractive mapping, the interpolation algorithm is conducted between the initial object and target object. Then the process of inbetween colour fractal images is obtained. Applying the fractal to colour morphing animation, a colour fractal-based morphing algorithm is provided. T...

The aim of this paper is to outline a multiple scale neural model to recognise colour images of textured scenes. This model combines colour and textural information in order to recognise colour texture images through the operation of two main components: a segmentation component composed of the colour opponent system (COS) and the chromatic segmentation system (CSS); and a recognition propertie...

Background: Preparing requires colouring to clarify or sharpen various tissue parts, especially cells. The use of synthetic dyes in preparations the long term can less impact both living things and environment. study aims obtain natural from morning glory flowers at optimal temperatures pH find out feasibility coloured using Morning Glory flower extract. Method: extraction process uses a macera...

Colour of natural objects perceived by humans is almost independent of the illuminant, the phenomenon known as colour constancy. Its mechanisms are not yet completely understood. Calculation of colour-constancy properties is difficult due to a non-linear neuronal activity implied by current models. An alternative is offered by modelling using artificial neural networks. In our study a neural ne...
