Purpose: Different views of an individuals’ image may be required for proper face recognition.   Recently, discrete cosines transform (DCT) based method has been used to synthesize virtual   views of an image using only one frontal image. In this work the performance of two different   algorithms was examined to produce virtual views of one frontal image.   Materials and Methods: Two new meth...

Introduction: Increasing in refer to computed tomography (CT-scan) imaging causes to increase in cumulative dose. Stereoradiography (EOS) is an X-ray imaging technology that, by eliminating scattering radiation, reduces patient's absorption dose and improves image quality.   Materials and Methods: This cross-sectional study was carried out in a hosp...

introduction. undoubtedly knowing the students views and characteristics have deep effect on certifying the subject and all other educational activities. then this study is an analytic, descriptive and cross sectional survey to certify the students educational needs in their own definitions and how to improve it. methods. the samples were 155 students of different medical groups that had passed...

introduction: with the increasing role of the internet as one of the most important sources of information on the one hand, and the enhancement of its usability on the other, it is necessary for web designers and developers to be familiar with the criteria that make a website usable. therefore, this paper aimed to provide knowledge about the interactivity, changeability , and non-textual conten...

there are several problems in matters concerning scientific explanation, the most important of which is offering a definition of explanation and classifying the different approaches taken in offering a model for scientific explanation. in this paper, we will go through the current approaches to explanation while presenting a definition of it. in their discussions about explanation, philosophers...

conclusion scout views may be useful in determining dose and image quality in ct scanning; however, it is necessary to first determine the most appropriate scout view for ct scans. background while using the automatic exposure control technique in computed tomography (ct), the scout view determines the radiation dose for the ct scan by taking anatomical morphology into consideration. objectives...
