Item Identifying Humans Through Gait Features(Springer Science and Business Media Deutschland GmbH, 2024) Anusha, R.; Jaidhar, C.D.Achieving robust human identification in visual surveillance is an ongoing and open research challenge in biometrics. In recent years, gait has added attention for its unique benefits when matched to other biometrics. Different gait-challenging conditions hinder the performance of gait recognition systems in real-world scenarios. The only solution to solve these challenges is to develop suitable features using available information sources. Enhancing the gait recognition system’s performance is the goal of this research, with a focus on frontal, speed-invariant, and clothing-invariant recognition. The proposed approaches demonstrate their capabilities through experimental results, outperforming existing methods of gait recognition. The solutions proposed in this paper increase gait recognition performance, making it applicable in real-world scenarios. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.Item On Human Identification Using Running Patterns: A Straightforward Approach(Springer Verlag service@springer.de, 2020) Anusha, R.; Jaidhar, C.D.Gait is a promising biometric for which various methods have been developed to recognize individuals by the pattern of their walking. Nevertheless, the possibility of identifying individuals by using their running video remains largely unexplored. This paper proposes a new and simple method that extends the feature based approach to recognize people by the way they run. In this work, 12 features were extracted from each image of a gait cycle. These are statistical, texture based and area based features. The Relief feature selection method is employed to select the most relevant features. These selected features are classified using k-NN (k-Nearest Neighbor) classifier. The experiments are carried out on KTH and Weizmann database. The obtained experimental results demonstrate the efficiency of the proposed method. © 2020, Springer Nature Switzerland AG.Item Clothing invariant human gait recognition using modified local optimal oriented pattern binary descriptor(Springer, 2020) Anusha, R.; Jaidhar, C.D.Human gait is a behavioral characteristic which has received a large amount of consideration in recent times as a biometric identifier. The clothing variance is one of the most common covariate influences which can influence the performance of gait recognition approach in real-world scenarios. This paper proposes a gait recognition approach proficient in choosing information characteristics for individual identification under different clothing conditions. The proposed method constitutes of addressing the feature extraction technique by introducing a binary descriptor called as Modified Local Optimal Oriented Pattern (MLOOP). In the proposed approach, initially, the feature vectors such as histogram and horizontal width vector are extracted from MLOOP descriptor, and then the dimensionality of the feature vector is reduced to remove the irrelevant features. The performance of MLOOP was accessed against its predecessors. Obtained experimental results demonstrate that the MLOOP descriptor performs better than the previous binary descriptors. Furthermore, the performance analysis of the proposed approach was assessed on OU-ISIR B treadmill gait database and CASIA B gait database. Broad investigations demonstrate the viability of the proposed technique. © 2019, Springer Science+Business Media, LLC, part of Springer Nature.Item Human gait recognition based on histogram of oriented gradients and Haralick texture descriptor(Springer, 2020) Anusha, R.; Jaidhar, C.D.Gait recognition is an evolving technology in the biometric domain; it aims to recognize people through an analysis of their walking pattern. One of the significant challenges of the appearance-based gait recognition system is to augment its performance by using a distinctive low-dimensional feature vector. Therefore, this study proposes the low-dimensional features that are capable of effectively capturing the spatial, gradient, and texture information in this context. These features are obtained by the computation of histogram of oriented gradients, followed by sum variance Haralick texture descriptor from nine cells of gait gradient magnitude image. Further, the performance of the proposed method is validated on five widely used gait databases. They include CASIA A gait database, CASIA B gait database, OU-ISIR D gait database, CMU MoBo database, and KTH video database. The experimental results demonstrated that the proposed approach could choose significant discriminatory features for individual identification and consequently, outperform certain state-of-the-art methods in terms of recognition performance. © 2020, Springer Science+Business Media, LLC, part of Springer Nature.
