Background and aims : Developing intelligent systems to prevent car accidents can be very effective in minimizing accident death toll. One of the factors which play an important role in accidents is the human errors. Fatigue driving is one of the cases that can cause errors and reduce accuracy in contorlling the vehicle. Methods : The signs of fatigue and sleepiness while driving is revea...
Video games are the most modern and sophisticated form of media in the present, which attracts millions of children and adults worldwide. The various effects of different types of video games on the psychological characteristics of gamers have been studied over the years. The serious effects of these games on cognitive and emotional characteristics such as memory, concentration, visual-motor sk...
Transmission of compressed video over error prone channels may result in packet losses, which can degrade the image quality. Error concealment (EC) is an effective approach to reduce the degradation caused by the missed information. The conventional temporal EC techniques are always inefficient when the motions of the video object are irregular. In this paper, in order to overcome this problem,...
introduction studying motility of biological objects is an important parameter in many biomedical processes. therefore, automated analyzing methods via microscopic videos are becoming an important step in recent researches. materials and methods in the proposed method of this article, a hypothesis testing function is defined to separate biological particles from artifact and noise in captured v...
Background & purpose: Autism spectrum disorder is a developmental neurological disorder characterized by impairment in social and communication interactions and repetitive behaviors. The increasing prevalence of this disorder has raised the need for research on its characteristics and treatment methods. The aim of this study was to investigate the effect of social stories using video modeling...
this paper is a part of study about the impact of the microclimate on the space use and the user’s behaviours. the purpose of our study is to get an in-depth understanding of how people use out door public spaces in different climatic conditions, how their behaviour and perception of the space change with the climatic variations. we have employed a multi-method approach which combines a “qualit...
generally human vision system searches for salient regions and movements in video scenes to lessen the search space and effort. using visual saliency map for modelling gives important information for understanding in many applications. in this paper we present a simple method with low computation load using visual saliency map for background subtraction in video stream. the proposed technique i...
macintosh direct laryngoscope has been the most widely used device for tracheal intubation. glidescope video laryngoscope (gvl) has been recently introduced as an alternative device for performing intubation; however, its validity in emergency settings has not been thoroughly evaluated. the aim of this study was to compare macintosh direct laryngoscope versus gvl for emergency endotracheal intu...
introduction automated methods for sperm characterization in microscopic videos have some limitations such as: low contrast of the video frames and possibility of neighboring sperms to touch each other. in this paper a new method is introduced for detection of sperms in microscopic videos. materials and methods in this work, first microscopic videos are captured from specimens of human semen. s...
Aims and Background: Helping patients with cardiac arrest depends on the speed and quality of treatment, so non-professional people generally are not able do such a treatment properly but any kind of training including interactive classrooms, television programs, newspapers and books can help nonprofessional people to save the life of these patients more effectively. The purpose of the study...
