Introduction: In health sector, image functions as a form of document that can convey a considerable amount of information. Employing this type of information can increase the effectiveness of the performance of medical experts. This study aimed to survey how health experts use medical images in their practice. Methods: This applied qualitative study was carried out in 1392 (2013). The study p...
Medical images show a great interest since it is needed in various medical applications. In order to decrease the size of medical images which are needed to be transmitted in a faster way; Region of Interest (ROI) and hybrid lossless compression techniques are applied on medical images to be compressed without losing important data. In this paper, a proposed model will be presented and assessed...
We consider dynamic scenes consisting of moving points whose motion is constrained to happen in one of a pencil of planes. This is for example the case when rigid objects move independently, but on a common ground plane (each point moves in one of a pencil of planes parallel to the ground plane). We consider stereo pairs of the dynamic scene, taken by a moving stereo system, that allow to obtai...
Advances in medical technology have greatly increased information density for imaging studies. This may result from increased spatial resolution facilitating greater anatomical detail, increased contrast resolution allowing evaluation of more subtle structures than previously possible, or increased temporal image acquisition rate. However, such technological advances, while potentially improvin...
in this paper a novel fuzzy scheme for medical x-ray image classification is presented. in this method, any image is partitioned in to 25 overlapping subimages and then shape-texture features are extracted from shape and directional information extracted from any subimage. in the classification stage, we apply a fuzzy membership to any subimage with respect to euclidean distance between feature...
introduction the diagnosis and separation of cancerous tumors in medical images require accuracy, experience, and time, and it has always posed itself as a major challenge to the radiologists and physicians. materials and methods we received 290 medical images composed of 120 mammographic images, ljpeg format, scanned in gray-scale with 50 microns size, 110 mri images including of t1-wighted, t...
