An experimental system was engineered and implemented in 100 copies inside a real banking environment comprising: dynamic handwritten signature verification, face recognition, bank client voice recognition and hand vein distribution verification. The main purpose of the presented research was to analyze questionnaire responses reflecting user opinions on: comfort, ergonomics, intuitiveness and other...
EFIT-V is a relatively new facial composite system, which has recently been introduced into a large number of UK police forces. The police procedure of working with EFIT-V directly claims that a witness should not be left alone and that he/she should work with a help of a police officer. However, some individuals may benefit from having a person to guide them, while others may find the presence of...
An efficient automatic facial expression recognition method is proposed. The method uses a set of characteristic features obtained by averaging the outputs from the Gabor filter bank with 5 frequencies and 8 different orientations, and then further reducing the dimensionality by the means of principal component analysis. The performance of the proposed system was compared with the full Gabor filter...
This study proposes a classification-based facial expression recognition method using a bank of multilayer perceptron neural networks. Six different facial expressions were considered. Firstly, logarithmic Gabor filters were applied to extract the features. Optimal subsets of features were then selected for each expression, down-sampled and further reduced in size via principal component analysis...
A novel method for facial expression recognition from sequences of image frames is described and tested. The expression recognition system is fully automatic, and consists of the following modules: face detection, maximum arousal detection, feature extraction, selection of optimal features, and facial expression recognition. The face detection is based on AdaBoost algorithm and is followed by the...
