Change Energy Image for Gait Recognition: An Approach Based on Symbolic Representation

Abstract

-Gait can be identified by observing static and dynamic parts of human body. In this paper a variant of gait energy image called change energy images (CEI) are generated to capture detailed static and dynamic information of human gait. Radon transform is applied to CEI in four different directions (vertical, horizontal and two opposite cross sections) considering four different angles to compute discriminative feature values. The extracted features are represented in the form of interval -valued type symbolic data. The proposed method is capable of recognizing an individual when he/she have variations in their gait due to different clothes they wear, in different normal conditions and carrying a bag. A similarity measure suitable for the proposed gait representation is explored for the purpose of establishing similarity match for gait recognition. Experiments are conducted on CASIA database B and the results have shown better recognition performance compared to some of the existing methods.

Symbolic Representation and Recognition of GAIT : An Approach Based on LBP of Split GAIT Energy Images

“…From the literature survey, we understand that the concept of symbolic data analysis has been well studied in the field of cluster analysis [7,8,9,10,11,12], shape analysis [13] and signature biometric applications [14]. Also suitability of symbolic data analysis approach for gait recognition is attempted recently in [15,16,17,18]. These unconventional techniques have proved that they outperform the conventional techniques in terms of performance and uncertainty.…”

Morpho-Spectral Recognition of Dense Urban Objects by Hyperspectral Imagery

“…The morphological library could be generated by intermediate symbolic representation (ISR) (e.g. Gauthier, 1999;Mohan Kumar andNagendraswamy, 2011) or using morphological toolbox (i.e. Feature Extraction, ENVI exelisvis 2008).…”
