From Real to Complex: Enhancing Radio-based Activity Recognition Using Complex-Valued CSI
ACM Transactions on Sensor Networks (TOSN), Volume 15, Issue 3Article No.: 35, Pages 1–32https://doi.org/10.1145/3338026Activity recognition is an important component of many pervasive computing applications. Radio-based activity recognition has the advantage that it does not have the privacy concern compared with camera-based solutions, and subjects do not have to carry ...

Identity recognition based on generalised linear regression classification for multi‐component images
In real‐world recognition applications, several poor situations such as varying environment, limited image information, and irregular status would lead performance degradation in recognition. To overcome the unexpected effects, the authors propose a ...

Robust Speaker Verification With Joint Sparse Coding Over Learned Dictionaries
IEEE Transactions on Information Forensics and Security (TIFS), Volume 10, Issue 10Pages 2143–2157https://doi.org/10.1109/TIFS.2015.2450674This paper presents a novel paradigm for speaker verification (SV) exploiting sparse representation (SR) over a learned dictionary. The proposed approach is intended to overcome the shortcomings of existing SR over an exemplar dictionary-based SV systems. ...

Facial Expression Recognition Based on Specific Regions Wavelet Decomposition, Local Directional Number Pattern and Sparse Representation
ICIG '13: Proceedings of the 2013 Seventh International Conference on Image and GraphicsPages 524–528https://doi.org/10.1109/ICIG.2013.111A new method for facial expression recognition is presented in this paper. Our method offers basically three benefits: first, it is combining regional compression with wavelet decomposition to preprocess the facial image, which can effectively remove ...
