In this paper, we proposed a novel fusion approach using global and local features. Colour Histogram (CH) is used as global feature and Block Bit Plane (BBP) as a local feature. For similarity measurement, distance d1 is used for CH features and BBPs are compared bit by bit using Hamming distance. Finally the overall similarity is computed as a weighted combination of global and local features. Particle swarm optimisation is used for optimisation of these weights. The proposed method is tested on 1000 and 3000 image database demonstrated significant improvement in precision and average recall rate compared to the current state of art methods.

Measurement of oxygen during the purification of glycerin – Case Study
Background informationGlycerin is a basic chemical which is used in creams and ointments, in antifreeze and brake fluid for vehicles, as a plasticizer, and as a base for paints and lacquers. Glycerin is produced as a by-product during the manufacture of soap. This was the main source of glycerin for many years. However, the production of biodiesel has increased greatly in the last decade, and glycerin is also a by-product of this process. All vegetable oils contain glycerin, a heavy trivalent alcohol. During the...

Using FTIR spectroscopy to measure hydrocarbon pollution in water
According to the World Health Organization (WHO) and UNICEF’s 2015 Progress on Sanitation and Drinking Water report almost 700 million people around the world don’t have access to clean drinking water . Poor water quality is beginning to return to the developed world too. The strain of population growth, intensified agricultural practices and continued industrial expansion have are all contributing to rising contamination levels in water supplies. Chlorinated Aromatic Hydrocarbons (CHCs) Pollute...
New from Lufft: The laser-based snow depth sensor SHM31
In future, one of our new products will support weather services, road operators, operators of winter sport areas and energy producers in the field of environmental monitoring: The SHM31 is able to deliver snow depths of up to 15 meters. It represents an advancement of the SHM30, which came onto the market in mid-2009.New snow height sensor SHM31 compared to its predecessor SHM30In contrast to the SHM30, which has one interface only, the new SHM31 snow depth sensor is equipped with the three communication interface...
Why choose Sialex over traditional salt based Ion Exchanger
We are regularly asked to compare our product with that of competitors. The market place for "Scale and Corrosion" control devices is large and there ae many different offerings. Customers select products based upon many parameters. Some parameters are emotional others purely objective. Most products for sale have positives to offer. Sometimes the message presented to the potential customer can be ambiguous and in some cases simply misleading. We do not claim to have the best solution for everyone. We do,...
