Palm prints are rich in features, can be easily acquired and hence different Palmprint features are used for the purpose of biometric identification. This paper presents analysis of wavelet coefficients for feature extraction of palm print images for biometry. A novel preprocessing technique for alignment of Palmprint images has been developed which allows the palm to be placed in any orientation...
A system to detect the direction of the odor source using a sensor array has been designed. The system uses the relation between the responses of different sensors to determine the direction of source. A novel dynamic direction detection method based on a neural network is presented for detecting direction of ethanol odor source. Odor-Compass can be used in applications like hazardous gas leakage...
