This study examined how forest edges, fruit display size, and fruit colour influenced rates of seed dispersal in an endemic, bird-dispersed, New Zealand mistletoe species, Alepis flavida. To examine rates of seed dispersal, fruit removal rates were compared between plants growing on forest edges and in forest interior, and also between two morphs of plants with different coloured fruits. Two as...

Observers inspected normal, high quality colour displays of everyday visual scenes while their eye movements were recorded. A large display change occurred each time an eye blink occurred. Display changes could either involve “Central Interest” or “Marginal Interest” locations, as determined from descriptions obtained from independent judges in a prior pilot experiment. Visual salience, as dete...

The primary goal of a colour characterization model is to establish a mapping from digital input values di (i=R,G,B) to tristimulus values such as XYZ. A good characterization model should be fast, use a small amount of data, and allow for backward mapping from tristimulus to di. This paper demonstrates implementations of three different colour characterization models, each tested on seven disp...

In a landmark statement, Crick and Koch [1] argued against primary visual cortex (V1) being the site for consciousness, citing the fact that V1 neurons did not display the properties necessary for colour constancy, a cornerstone of our conscious experience. Colour constancy is what makes the redness of a red apple stable under changing illumination. All proposed mechanisms for colour constancy ...

statement of problem: acrylic teeth of dentures are prone to discoloration due to frequent exposure to different colouring solutions in the oral environment. thus, in order to maintain their aesthetic appearance, they must possess high colour stability while exposed to colorant solutions. objectives: to compare the colour stability of three different brands of acrylic teeth following immersion ...

In this paper, we explore a number of techniques for two-dimensional visualisation of temporal social network data, with the goal of providing feedback on the group dynamics of government planning workshops. These techniques include the use of position and colour for displaying temporal information, as in colour-coded bar charts or sequence diagrams. While it is possible to display temporal inf...

We examined how stream/bounce event perception is affected by motion correspondence based on the surface features of moving objects passing behind an occlusion. In the stream/bounce display two identical objects moving across each other in a two-dimensional display can be perceived as either streaming through or bouncing off each other at coincidence. Here, surface features such as colour (Expe...

To investigate the time course of attentional object selection processes in visual search tasks where targets are defined by a combination of features from the same dimension, we measured the N2pc component as an electrophysiological marker of attentional object selection during colour/colour conjunction search. In Experiment 1, participants searched for targets defined by a combination of two ...

carotenoids are the main pigments of tomato, of which 93% is lycopene. lycopene has desirable physiological effects in human sush as cancer prevention. recent years, because of harmful side effects of synthetic colouring agents used in food products, employing of natural food colouring agents has become very important. in this research firstly, solvent extraction method was used for tomato caro...
