Face Recognition using Hough Peaks extracted from the significant blocks of the Gradient Image
Arindam Kar, Debotosh Bhattacharjee, Dipak Kumar Basu +2
This paper proposes a new technique for automatic face recognition using integrated peaks of the Hough transformed significant blocks of the binary gradient image. In this approach…
A Face Recognition approach based on entropy estimate of the nonlinear DCT features in the Logarithm Domain together with Kernel Entropy Component Analysis
Arindam Kar, Debotosh Bhattacharjee, Dipak Kumar Basu +2
This paper exploits the feature extraction capabilities of the discrete cosine transform (DCT) together with an illumination normalization approach in the logarithm domain that inc…
A Gabor block based Kernel Discriminative Common Vector (KDCV) approach using cosine kernels for Human Face Recognition
Arindam Kar, Debotosh Bhattacharjee, Dipak Kumar Basu +2
In this paper a nonlinear Gabor Wavelet Transform (GWT) discriminant feature extraction approach for enhanced face recognition is proposed. Firstly, the low-energized blocks from G…
The geometric phase and the geometrodynamics of relativistic electron vortex beams
Pratul Bandyopadhyay, Banasri Basu, Debashree Chowdhury
We have studied here the geometrodynamics of relativistic electron vortex beams from the perspective of the geometric phase associated with the scalar electron encircling the vorte…
Rational extension and Jacobi-type {\boldmath{}} solutions of a quantum nonlinear oscillator
Axel Schulze-Halberg, Barnana Roy
We construct a rational extension of a recently studied nonlinear quantum oscillator model. Our extended model is shown to retain exact solvability, admitting a discrete spectrum a…
Local Orthogonality provides better upper bound for Hardy's nonlocality
Subhadipa Das, Manik Banik, Md. Rajjak Gazi +2
The amount of nonlocality in quantum theory is limited compared to that allowed in generalized no-signaling theory [Found. Phys. 24, 379 (1994)]. This feature, for example, gets ma…
