Chemical and biological (CB) detection technologies have become more mature, and some are now available for operational use. As the sensor availability has increased, so too has the realization that the interpretation of the sensor output is nontrivial. The sensor data can be coupled with non-sensor information about the operational and environmental conditions prevailing at the time of the sen...

This paper presents an efficient human recognition system which makes use of vein patterns obtained from the back of the hand. It has used a new reflection-based image capturing environment to ensure high quality images through least effort and cost. The proposed recognition system automatically detects the region of interest (ROI) from the image and does the necessary preprocessing to extract ...

Robust pattern recognition within the Bayesian framework for scene segmentation/boundary detection is oftentimes hampered by the presence of textures within natural images. In order to improve segmentation/boundary detection on natural images, it is necessary to combine multiple features eeectively. This paper introduces two algorithms for combining both color and texture features to assist bou...

An odour is the description of the sensation perceived when volatile chemicals are sensed by the biological nose. The odours that we perceive in the world around us arise through the interaction of molecules with sensory cells located in our nose. Typically, the odour of a flower or of a foodstuff or other natural material consists of a complex mixture of molecules present in different concentr...
