[IEEE 2018 2nd International Conference on Trends in Electronics and Informatics (ICOEI) - Tirunelveli (2018.5.11-2018.5.12)] 2018 2nd International Conference on Trends in Electronics and Informatics (ICOEI) - SmartMobiCam: Towards a New Paradigm for Leveraging Smartphone Cameras and IaaS Cloud for Smart City Video Surveillance
摘要： Cloud and mobile computing domains have become quite popular these days. Besides, the ubiquitous smartphones are increasingly becoming a dominant platform for collaborative sensing, so we built an android application SmartMobiCam, which aids in forming the robust and scalable Smart city video surveillance system which is critical for upgrading the urban areas. The application obtains video feed, images and sound clips from the users and then uses cloud services for video enhancement and restoration of the content and provides it to all subscribers including police investigators. The application is explained with detailed architectural and technological choices. Performance analysis shows that the proposed application performs well and outperforms the traditional surveillance system.

Recent Advances in Image and Video Coding || Approach to Super-Resolution Through the Concept of Multicamera Imaging
摘要： Super-resolution consists of processing an image or a set of images in order to enhance the resolution of a video sequence or a single frame. There are several methods to apply super-resolution, from which fusion super-resolution techniques are considered to be the most adequate for real-time implementations. In fusion, super-resolution and high-resolution images are constructed from several observed low-resolution images, thereby increasing the high-frequency components and removing the degradations caused by the recording process of low-resolution imaging acquisition devices. Moreover, the proposed imaging system considered in this work is based on capturing various frames from several sensors, which are attached to one another by a P × Q array. This framework is known as a multicamera system. This chapter summarizes the research conducted to apply fusion super-resolution techniques to select the most adequate frames and macroblocks together with a multicamera array. This approach optimizes the temporal and spatial correlations in the frames and reduces as a consequence the appearance of annoying artifacts, enhancing the quality of the processed high-resolution sequence and minimizing the execution time.

[IEEE 2018 IEEE 13th Image, Video, and Multidimensional Signal Processing Workshop (IVMSP) - Aristi Village, Zagorochoria, Greece (2018.6.10-2018.6.12)] 2018 IEEE 13th Image, Video, and Multidimensional Signal Processing Workshop (IVMSP) - Video Deconfounding: Hearing-Aid Inspired Video Enhancement
摘要： We introduce a set of techniques for selective amplification of video subjects that are largely hidden from view by confounding light paths, such as daylight reflections from tinted automobile windows, reflections from windows and screens when imaging outdoor scenes at night from indoors, and reflected light from fluid surfaces. In these situations, the subject of interest is represented by only a small fraction of the light being captured at each pixel. We show that enhancement approaches commonly employed for selective amplification of speech in audio applications can serve as the basis for selective amplification of hidden objects in video streams.
