Journal Article
Effect of two selected yogic breathing techniques of heart rate variability.
TL;DR: The results suggest that kapalabhati modifies the autonomic status by increasing sympathetic activity with reduced vagal activity and suggests that HRV is a more useful psychophysiological measure than heart rate alone.
Journal ArticleDOI
ECG coding by wavelet-based linear prediction
A. G. Ramakrishnan,Saikat Saha +1 more
TL;DR: The significant feature of the proposed technique is that, while the error is nearly uniform throughout the cycle, the diagnostically crucial QRS region is kept free of maximal reconstruction error.
Proceedings ArticleDOI
Automation of differential blood count
Neelam Sinha,A. G. Ramakrishnan +1 more
TL;DR: A technique for automating the differential count of blood takes, as input, color images of stained peripheral blood smears and identifies the class of each of the white blood cells (WBC), in order to determine the count of cells in each class.
Journal ArticleDOI
Word level multi-script identification
TL;DR: The combination of Gabor features with nearest neighbor or SVM classifier shows promising results; i.e., over 98% for bi-script and tri-script cases and above 89% for the eleven-script scenario.
Journal ArticleDOI
Epoch Extraction Based on Integrated Linear Prediction Residual Using Plosion Index
TL;DR: The proposed dynamic plosion index (DPI) algorithm, based on integrated linear prediction residual (ILPR) which resembles the voice source signal, is tested for its robustness in the presence of additive white and babble noise and on simulated telephone quality speech.
