Special Issue Information

Dear Colleagues,

All media faces the general problem of the coding of the information for transmission to the final user, this is a particular problem in relation to the emergence of new media, mobile media and social media, and the general and diffuse use of short videos in many social and crowdsourced information systems, the advent of stereo/multiview vision systems and the availability of RGB-D cameras in vision systems, able to reproduce 3D objects in the scene. Video compression techniques, formerly defined as techniques and algorithms able to provide efficient solutions to represent video data in a compact form to be delivered in a cost-effective way through a given communication link to a destination site, recently have shifted to assume a more complex definition in which many different approaches are adopted to solve the specific problem of optimization in the information interchange between peers or in broadcasting networks. This optimization is influenced by the quality of the received video, the data rate required to transmit the information, the device power consumption, the algorithm complexity, the scalability and the general quality of experience in the creation of videos.

The general problem of coding is always getting more challenging because several coding techniques have to coexist in different application scenarios. Even if there is plenty of video coding systems that perform well in specific applications, the unitary description of the problem of video coding is still far from being defined; its domain can be located in a multidimensional space in which different videos with different characteristics in terms of frame rates, resolutions, duration, bandwidths, contribute to the specific application framework to allow the definition of new and fascinating applications.

Submissions to this Special Issue on Image/Video Processing and Coding are solicited to represent a snapshot of the field’s development by covering a range of topics that include, but are not limited to, new methods, algorithms, solutions and applications in the areas:

  • Image/video analysis
  • Semantic information extraction in video
  • Action analysis, recognition and coding in video
  • Video coding algorithms
  • High-efficiency video coding
  • Multiview video coding
  • 3D video analysis/processing/coding
  • Content-based video coding
  • Stereo video coding
  • Scaleable video coding
  • Predictive video coding
  • Video composition from different sources
  • HW implementation of coding systems
  • Emerging algorithms for image and video processing
  • Model-based video coding
  • Perceptual video coding
  • Statistic-based video coding
  • Deep learning and CNN approaches to video coding
  • Low complexity video coding

With the increase in life expectancy, one of the most important topic for scientific research, especially for the elderly, is good nutrition. In particular, with an advanced age and health issues because disorders such as Alzheimer and dementia, monitoring the subjects’ dietary habits to avoid excessive or poor nutrition is a critical role. Starting from an application aiming to monitor the food intake actions of people during a meal, already shown in a previously published paper, the present work describes some improvements that are able to make the application work in real time. The considered solution exploits the Kinect v1 device that can be installed on the ceiling, in a top-down view in an effort to preserve privacy of the subjects. The food intake actions are estimated from the analysis of depth frames. The innovations introduced in this document are related to the automatic identification of the initial and final frame for the detection of food intake actions, and to the strong revision of the procedure to identify food intake actions with respect to the original work, in order to optimize the performance of the algorithm. Evaluation of the computational effort and system performance compared to the previous version of the application has demonstrated a possible real-time applicability of the solution presented in this document.

In recent years, the rise of car accident fatalities has grown significantly around the world. Hence, road security has become a global concern and a challenging problem that needs to be solved. The deaths caused by road accidents are still increasing and currently viewed as a significant general medical issue. The most recent developments have made in advancing knowledge and scientific capacities of vehicles, enabling them to see and examine street situations to counteract mishaps and secure travelers. Therefore, the analysis of driver’s behaviors on the road has become one of the leading research subjects in recent years, particularly drowsiness, as it grants the most elevated factor of mishaps and is the primary source of death on roads. This paper presents a way to analyze and anticipate driver drowsiness by applying a Recurrent Neural Network over a sequence frame driver’s face. We used a dataset to shape and approve our model and implemented repetitive neural network architecture multi-layer model-based 3D Convolutional Networks to detect driver drowsiness. After a training session, we obtained a promising accuracy that approaches a 92% acceptance rate, which made it possible to develop a real-time driver monitoring system to reduce road accidents.
