AbstractThe hardware challenges associated with light-field (LF) imaging has made it difficult for consumers to access its benefits like applications in post-capture focus and aperture control. Learning-based techniques which solve the ill-posed problem of LF reconstruction from sparse (1, 2 or 4) views have significantly reduced need complex hardware. video poses a special challenge as acquiri...

By 2022, we expect video traffic to reach 82% of the total internet traffic. Undoubtedly, abundance video-driven applications will likely lead percentage a further increase in near future, enabled by associate advances devices' capabilities. In response this ever-growing demand, Alliance for Open Media (AOM) and Joint Video Experts Team (JVET) have demonstrated strong renewed interest developin...

The intriguing characteristics of chaotic maps have prompted researchers to use these sequences in watermarking systems to good effect. In this paper we aim to use a tent map to encrypt the binary logo to achieve a like-noise signal. This approach makes extraction of the watermark signal by potential attacker very hard. Embedding locations are selected based on certain principles. Experimental ...

Background and Objectives: Identification of surgical instruments in laparoscopic video images has several biomedical applications. While several methods have been proposed for accurate detection of surgical instruments, the accuracy of these methods is still challenged high complexity of the laparoscopic video images. This paper introduces a Surgical Instrument Detection Framework (SIDF) for a...

Despite tremendous popularity of video games, there have been concerns about their detrimental effects on children. The game rating systems were developed to assist parents in monitoring their children’s gaming experiences. This paper explores how parents in Iran, as a society without established media rating systems, control their children’s gaming experiences. Mixed methods of semi-structured...

The present paper aimed to study the effect of pairwise video check feedback (including the observation of external pattern of skill performance and performing the skill simultaneously) on the learning on acquisition and learning of eye-hand coordination skill. Computer skill of eye-hand coordination skill was the tool used in this study. 24 subjects were randomly selected and equally divided...
