This paper present a method for image segmentation, which is an adaptation of the classical active contours algorithm, also called "snakes", using a new internal energy approach. The classical model computes the energy function based on changes in gradient values, thus determining the detection of the object's edges. In the proposed model, the active(More)
This paper presents a variation of the classic algorithm of active contours in order to improve the visualization of 3D reconstruction of anatomical structures in medicine. This 3D reconstructions are made from the obtained contours. This variation of active contour enables a better behavior of them.Other authors have already used snakes (active contours)(More)
Health Care Information Systems (HCIS) have provided the opportunity and tools to estimate, interpret, observe and better understand newest health care problems. In this way, Information and Communication Technologies permit researchers to sustain greater benefits such as decision support systems, protecting sensitive patient data, integration of complex(More)
Too many people suffer from noise levels that scientists and health experts consider to be unacceptable, where most people become annoyed, where sleep is disturbed and where adverse health effects are to be feared. The present paper centers on inferring individuals annoyance level caused by noise exposure. The starting point of our thoughts is the(More)
