This paper presents Gaussian and impulse noise filters for eliminating mixed noise in images. For Gaussian filter, the fuzzy set called "small" is derived to represent the disorder in a pixel arising out of neighborhood corrupted with Gaussian. The expression for correction is developed based on the intensity of the central pixel and the membership(More)
Jackstone calculi are urinary tract stones that have a specific appearance resembling toy jacks. They are almost always composed of calcium oxalate dihydrate consist of a dense central core and radiating spicules. They are usually light brown with dark patches and are usually described to occur in the urinary bladder and rarely in the upper urinary tract.(More)
The advancement of technology in satellite system has drastically improved the quality of images which we call high resolution images. Today we have many satellites which provide high resolution images such as QUICKBIRD, IKONOS,WORLD-VIEW etc. High resolution provides much greater detail of information such as buildings or trees etc. can be seen clearly.(More)
There exist many algorithms for producing the spanning trees of a graph with better time and space complexities. In this research study, we are presenting a study on number of spanning trees and a technique based on the basic cycle to find the number of spanning trees and also the structure of all the spanning trees of a labeled and undirected graph.
This article is concerned with the development of some stochastic models better suited to describe the observed distributions of the menstruating interval relating to last closed-birth interval of two types of females. In this context, two models suited for couples using or not using contraception have been proposed. In the first case, the model assumes a(More)
Embryonal cell carcinoma affects young males in the prime of their life with majority of tumours already having metastasised at the time of diagnosis. Subcutaneous metastasis from embryonal carcinoma is rare and is associated with widespread disease and poor prognosis. We report a case of 22-year-old male who presented with haemoptysis and skin nodules.(More)
INTRODUCTION The reported number of new leprosy patients has barely changed in recent years. Thus, additional approaches or modifications to the current standard of passive case detection are needed to interrupt leprosy transmission. Large-scale clinical trials with single dose rifampicin (SDR) given as post-exposure prophylaxis (PEP) to contacts of newly(More)
