Recently, intelligent video surveillance applications have become essential in public security by the use of computer vision technologies to investigate and understand long video streams. Anomaly detection and classification are considered a major element of intelligent video surveillance. The aim of anomaly detection is to automatically determine the existence of abnormalities in a short time period. Deep reinforcement learning (DRL) techniques can be employed for anomaly detection, which integrates the concepts of reinforcement learning and deep learning enabling the artificial agents in learning the knowledge and experience from actual data directly. With this motivation, this paper presents an Intelligent Video Anomaly Detection and Classification using Faster RCNN with Deep Reinforcement Learning Model, called IVADC-FDRL model. The presented IVADC-FDRL model operates on two major stages namely anomaly detection and classification. Firstly, Faster RCNN model is applied as an object detector with Residual Network as a baseline model, which detects the anomalies as objects. Besides, deep Q-learning (DQL) based DRL model is employed for the classification of detected anomalies. In order to validate the effective anomaly detection and classification performance of the IVADC-FDRL model, an extensive set of experimentations were carried out on the benchmark UCSD anomaly dataset. The experimental results showcased the better performance of the IVADC-FDRL model over the other compared methods with the maximum accuracy of 98.50% and 94.80% on the applied Test004 and Test007 dataset respectively.

Obstructive sleep apnea (OSA) is a common disease that leads in notorious symptoms and comorbidities. Although general measures are important, continuous positive airway pressure (CPAP) is the best treatment option. However, compliance can be suboptimal and telemedicine may play a role to improve it. Areas covered: Review authors searched EMBASE, PubMed and Cochrane data bases using the following keywords: continuous positive airway pressure, Obstructive sleep apnea, telemedicine, respiratory telemedicine, information and communication technology. Papers published between 2000 and 2016 in English language were considered. Expert commentary: To improve OSA management, there is a pressing need to develop new cost-effective strategies, particularly those related to OSA treatment, from measures such as lifestyle changes to CPAP use. Two broad strategies should be implemented: 1) adequate pre-, peri-, and post-titration measures to ensure correct diagnosis, adequate training, and appropriate support during follow up; and 2) the use of technological advances including both the optimization of CPAP devices and the use of telemedicine, specially focused on the first days or weeks of treatment. Telemedicine can help with these processes, especially when it is personalized to the needs of each patient group.
