wastewater from molasses processing contains a large amount of coloured substances that give a recalcitrant dark brown colour and high organic load to the effluent. photocatalytic decolourization of molasses wastewater was performed using titanium dioxide catalyst coated on the surface of south african natural zeolite using the solid-solid dispersion method. addition of hydrogen peroxide as an ...

This paper proposes a method to extract the emotional impact of images. Emotions are often associated with facial expressions, but we decided consider other features as first emotional characteristic of natural images, which, in general, does not contain faces. For a seek of generally we have built a new image database composed of a large variety of low semantic images. We used colour images be...

The study of colour and colour precursors in cane sugar has been an important research area at Sugar Processing Research Institute for many years. Previous studies on isolating colourant precursors have relied on various liquid-liquid extraction procedures, time consuming methods requiring large amounts of sample and solvent. Four methods were examined for the identification of raw sugar colour...

The large number of publications in the field of extraction, purification, modification, and process optimization of natural dyes and their application on textiles demonstrates the revival of natural dyes on textile coloration. The use of natural dyes is growing in popularity because of the quality of the natural dyestuff obtained, the environmental compatibility of the dyes and the substantial...

In this paper an approach to road extraction in open landscape regions from IKONOS multispectral imagery is presented which combines a line-based approach for road extraction with area-based colour segmentation. Existing road databases are used in two ways: firstly, to estimate scene dependent parameters of the line-based approach and secondly to exclude non road regions from the extraction, al...

Automated close-range photogrammetric measurement has traditionally been associated with expensive specialist cameras and usually requires highly controlled image illumination conditions. In the past few years, however, there has been a significant amount of research into the development of automated routines and algorithms that support the employment of consumer-grade colour digital cameras fo...

*, **, *** Department of Computer Science and Engineering, Annamalai University, Tamilnadu, India ABSTRACT Sign Language is a natural way of communication for deaf and mute people around the world. They use different hand gestures to communicate with normal people everywhere. In this paper, a real time finger counter is proposed for counting the number of fingers (1-5) shown in a hand gesture. ...
