A Fully Automated Gridding Technique for Real Composite cDNA Microarray Images
Autor: Steffy Maria Joseph, P. S. Sathidevi
Publikováno v: IEEE Access, Vol 8, Pp 39605-39622 (2020)
Genome-wide screening using microarrays of DNA will be of great use in the early diagnosis of diseases such as cancer and HIV. It also makes use of gene discovery, pharmacogenomics, toxicogenomics, and nutrigenomics for other applications. A DNA micr

Speaker Verification from Codec-Distorted Speech Through Combination of Affine Transform and Feature Switching
Autor: M. S. Athulya, P. S. Sathidevi
Publikováno v: Circuits, Systems, and Signal Processing. 40:6016-6034
A high-performance speaker verification system from codec-distorted speech is developed and implemented in this paper. Apriori knowledge of the type of the speech codec is utilized in this. Code excited linear prediction-based codec which is one of t

Mel Scale-Based Linear Prediction Approach to Reduce the Prediction Filter Order in CELP Paradigm
Autor: P. S. Sathidevi, M. S. Arun Sankar
Publikováno v: Circuits, Systems, and Signal Processing. 40:3813-3835
This paper proposes a novel method to reduce the order of prediction filter from 10 to 7 in Code Excited Linear Prediction (CELP) coding framework by the inclusion of psychoacoustic Mel scale into Linear Predictive Coding (Mel-LPC). Efficient quantiz

Design of MELPe-Based Variable-Bit-Rate Speech Coding with Mel Scale Approach Using Low-Order Linear Prediction Filter and Representing Excitation Signal Using Glottal Closure Instants
Autor: M. S. Arun Sankar, P. S. Sathidevi
Publikováno v: Arabian Journal for Science and Engineering. 45:1785-1801
In this paper, we propose a variable-bit-rate speech codec-based on mixed excitation linear prediction enhanced (MELPe) with an average bit rate of 2 kbps and with a better representation of excitation signal. The order of the prediction filter in ME

AN EFFICIENT PSO OPTIMIZED INTEGRATION WEIGHT ESTIMATION USING D-PRIME STATISTICS FOR A MULTIBIOMETRIC SYSTEM
Autor: S. M. Anzar, P. S. Sathidevi
The efficiency of a multibiometric system can be improved by weighting the scores obtained from the degraded modalities in an appropriate manner. In this paper, we propose an efficient PSO (Particle Swarm Optimization) based integration weight optimi
