This paper proposes a goodness function for colour segmentation, which allows to predict whether the segmented regions will be stable against noise, variation of lighting, and change of viewpoint. As such a measure, colour saliency defined from average border contrast is proposed. While the idea to maximise border contrast in segmentation is not novel per se, it is shown here empirically that m...

a participatory rural appraisal technique (prat) was used to obtain information from 132 randomly selected turkey farmers in two out of four agricultural development zones in kwara state, nigeria. data were obtained on socio-occupational status of farmers, their production objectives, experience, flock structure, management practices, marketing and consumption of turkey eggs. the results showed...

Dry thermal treatments of wood samples were carried out at 160 and 200 °C. After each treatment, the samples were irradiated using a strong UV emitter mercury lamp, and the colour change was then evaluated. For control, untreated samples were also irradiated using the same mercury lamp. Results showed that the extractive content of the wood played an important role in the colour change not only...

Heat and mass transfer phenomena that take place during frying cause physicochemical changes, which affect the colour and surface of the fried products. The effect of frying temperature on the colour changes and heat transfer during deep fat frying of garlic has been investigated. The colour scale parameters redness (a*), yellowness (b*) and lightness (L*), and color change intensity (∆E) were ...

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)...

Considering massless u and d quarks, and massive (150 MeV) s quarks in a bag with the bag pressure constant B1/4 = 145 MeV, a colour-singlet grand canonical partition function is constructed for temperatures T = 1−30 MeV. Then the stability of finite size strangelets is studied minimizing the free energy as a function of the radius of the bag. The colour-singlet restriction has several profound...

In agreement with the principles of the relativistic model proposed by Creutzfeldt et al., with the photometric rule (lightness anchoring rule) and with the influence of simultaneous contrast in the appearance of a visual scene, we propose a first-stage mechanism yielding substantial colour constancy. We have defined a set of first-stage colour descriptors, and to test their utility, we have pe...
