This study presents a 2-stage heartbeat classifier of supraventricular (SVB) and ventricular (VB) beats. Stage 1 makes computationally-efficient classification of SVB-beats, using simple correlation threshold criterion for finding close match with a predominant normal (reference) beat template. The non-matched beats are next subjected to measurement of 20 basic features, tracking the beat and r...

Autoassociative morphological memories (AMM) are memory models that use operations of mathematical morphology for the storage and recall of pattern associations. These models can be very well de ned in a mathematical structure called complete lattice. In this paper, we introduce the Brouwerian autoassociative morphological memories (BAMMs) that are de ned on a complete Brouwerian lattice. The a...

Abstract: Comparing probability or possibility distributions is important in many elds of information processing under uncertainty. In this paper we address the question of de ning and computing Hausdor distances between distributions in a general sense. We propose several dilations of distributions, and exhibit some links betweenLévy-Prokhorovdistances anddilation-baseddistances. In particular...

In image analysis most commonly used technique is edge detection, probably there are many edge detection techniques are available in the literature of detecting edges .in order to avoid the discontinuities in the image brightness among different regions of an image .we are proposing two edge detection algorithm that are canny edge detection algorithm and fuzzy mathematical morphology based edge...

Cell segmentation is one of important steps in the automatic white blood cell differential counting. In this paper, we propose a technique to segment singlecell images of white blood cells in bone marrow into two regions, i.e., nucleus and non-nucleus. The segmentation is based on the fuzzy C-means clustering and mathematical morphology. The segmentation results are compared to an expert’s manu...

Phase contrast X-ray tomography (PCT) enables the study of systems consisting of elements with similar atomic numbers. Processing datasets acquired using PCT is nontrivial because of the low-pass characteristics of the commonly used single-image phase retrieval algorithm. In this study, we introduce an image processing methodology that simultaneously utilizes both phase and attenuation componen...

A novel microscopic Shape-From-Polarization (SFP) 3D shape reconstruction method is proposed, in which degree of polarization calculated using Polarized Bidirectional Reflectance Distribution Function (PBRDF) to overcome azimuthal ambiguity for both specular and diffuse scenes. Based on the polarization, a modulation microscopy oriented variational model established estimate surface normal vect...
