The goal of the work reported in this dissertation is to develop methods for the acquisition and reproduction of high quality digital colour images. To reach this goal it is necessary to understand and control the way in which the different devices involved in the entire colour imaging chain treat colours. Therefore we addressed the problem of colorimetric characterisation of scanners and print...

Non-destructive quality inspection of fruits provides quality products for domestic consumption as well as for export markets, increasing consumer/buyer confidence. It provides assurance of quality and subsequent value addition. A major thrust of current research is towards the development of quality inspection systems for improved sorting and automated quality control. Machine Vision inspectio...

AIM The role of transoesophageal echocardiography in cardiac interventional structural procedures is well established and appreciated. However, the need for general anaesthesia (GA) throughout the procedure remains a controversial issue. The aim of the present study is to assess the feasibility and imaging quality of using a transnasal microrobe that allows the usage of conscious sedation in pa...

Th is study was designed to investigate whether inclusions of coenzyme Q10, alpha lipoic acid and their combination into diets of hens improve egg quality characteristics. Forty-eight, 33 weeks old Lohmann Brown hens were assigned randomly to four groups of 12 hens each and fed either a basal diet or basal diet supplemented with 2 g/ kg coenzyme Q10, 0.4 g/kg alpha lipoic acid and 2 g/kg coenzy...

A study was conducted to evaluate the quality of the leather from five different cultivars (Red Fleshed, Allahabad Safeda, Lucknow-49, Chittidar, Apple Colour of guava. Leather quality was also observed using three different recipes for its preparation. The study revealed that organoleptic quality (i.e. colour, flavour, taste, texture and overall acceptability) of leather decreased gradually wi...

Digitally, panoramic pictures can be assembled from several individual, overlapping photographs. While the geometric alignment of these photographs has retained a lot of attention from the computer vision community, the mapping of colour, i.e. the correction of colour mismatches, has not been studied extensively. In this article, we analyze the colour rendering of today’s digital photographic s...

Tea-ginger drink was selected for evaluation due to its nutraceutical potential. Panelists rated preference for drinks prepared from tea, ginger, and tea+ginger powder for colour, taste, and aroma. The obtained data were evaluated using analysis of variance, principal component analysis, and agglomerative hierarchical clustering. Also the colour preference scores were evaluated against instrume...

The orientation of this research was to evaluate the classic parameters regarding the external and internal quality of tomato fruits cv. 'Brilliant' at different stages of maturity and to define the dynamics of their changes during the ripening in storage at 18 C. Principal component analysis (PCA) and multivariate canonical discriminant analysis (DA) were used to classify tomato samples accor...
