Quantitative microscopy has strengthened conventional diagnostic scheme through better understanding of microscopic features from clinical perspective. Towards this, pathological image analysis has gained immense significance among medical fraternity through visualization and quantitative evaluation of clinical features. Till today pathological inspection(More)
The objective of this paper is to introduce a computer assisted prediction of malaria infection particularly Plasmodium vivax based on the morphological and textural information. Here erythrocytes have been segmented from light microscopic images of peripheral blood smear using marker controlled watershed followed by pre-processing. Thereafter texture and(More)
This paper aims at introducing a new approach to Plasmodium vivax (P. vivax) detection from Leishman stained thin blood film. This scheme follows retrospective study design protocol where patients were selected at random in the clinic. The scheme consists of two main stages - firstly artefacts reduction, and secondly fuzzy divergence based segmentation of(More)
The paper provides a novel approach to represent cooperative/competitive interactions among coexisting emotions by a recurrent neural dynamics, and proposes a scheme for parameter estimation of the dynamics from the facial expressions of the subjects, psychologically excited by audio-visual stimulus taken from select commercial movies. Conditions for(More)
This paper aims at introducing a textural pattern analysis approach to Plasmodium vivax (P. vivax) detection from Leishman stained thin blood film. This scheme follows retrospective study design protocol where patients were selected at random in the clinic. The scheme consists of four stages – artefacts reduction, fuzzy divergence-based segmentation of P.(More)
This paper addresses the development of content-based medical image retrieval system for automated leukocyte recognition from microscopic images of peripheral blood smears. The proposed methodology ensembles Quaternion Fourier transform based segmentation and Gabor-wavelet describing textural features of leukocytes. This technique is computationally(More)
The paper presents an analysis of chaos, limit cycles and stability in the antigen-antibody interactive dynamics. Both cooperation and competition of antibodies are considered in the dynamics. The classical approach of Lyapunov has been employed here for the stability analysis of the dynamics. Computer simulations have been undertaken to support the results(More)
The paper attempts to model the interactive dynamics of competitive/co-operative emotions, aroused by audio-visual stimulus. Parameter variations of the dynamics results in three specific dynamic behavior including chaos, limit cycles and stability. An analysis of the dynamics yields the parametric conditions for stability and chaos. Known audio-visual(More)
