摘要：
Live video streaming process consumes very large data storage and takes very long time, so it requires big data storage and computing infrastructures for implementation. Accordingly, the use of cloud computing is becoming a common practice solution for streaming service providers. This work proposes a new scheme to manage the quality of experience (QoE) for live video streaming viewers, aimed directly at cloud computing environments. This scheme proposes to make optimal usage of cloud computing resources and quality services to meet the quality of experience (QoE) requirements of the live video streaming viewers without considering another cost to the video service provider. We examine the user’s quality of experience using dynamic adaptive streaming HTTP (DASH) technique. Then, we present and derive three important performance indicators which effect on viewer’s QoE namely: startup delay, deadline time (time nulling including null duration and number of null time), and bit rate level variations. The simulation results show that the tested indication parameters do not need to access the service providers in order to manage QoE of viewers neither do not need to insert them into the video streaming client software to determine the user experience in live video streaming. So, we believe that our proposed scheme and the performance indicators that studied in our work can serve as useful and light-weight tools for live video streaming service provider to monitor and control their quality of services.

摘要：
This paper presents an algorithm for reading two digital video clocks of broadcast basketball videos by using context-aware pixel periodicity method and deep learning technique. Reading two digital video clocks is a very challenge problem as a difficulty special case of reading video text. The first challenge task is the clock digit localization. The existing pixel periodicity is a very good method for localizing second-digit place if a single clock is in video, but it is not applicable to localizing two second-digit places. This paper proposes a context-aware pixel periodicity method to identify the second-pixels of each clock based on the domain knowledge of digital video clocks. The second challenge task is clock-digit recognition. For this task, the CNN-based procedures are proposed to recognize clock digits. The experimental results show that the proposed algorithm can achieve 100% of accuracy in both localization and recognition for two clocks at very low computational cost by using very short input clips.

摘要：
With the wide deployment of the video sensor network and the rapid development of video spatialization technology, the large volume of complex GeoVideo data necessitates improvements in the application efficiency of the GeoVideo database and GeoVideo surveillance system. Traditional storage management approaches focus on the optimization of access to the GeoVideo stream. However, they suffer from poor management of the diverse movement processes contained within it; for example, they cannot support associative queries or comprehensive analysis of multi-type GeoVideo data in complex geographic environments. This paper takes physical movement process in GeoVideo as a new type of object and carries out an objectified organization of the heterogeneous GeoVideo data around it (including the video stream, spatial references, interpretations of the video data, and the overall scene) in a Not only SQL-Structured Query Language (NoSQL-SQL) hybrid GeoVideo database. This paper systematically explores the hybrid spatiotemporal indexes and multi-modal retrieval methods around movement processes, which enrich the query modes of the GeoVideo data. A prototype implementation and experimental analysis are presented to prove the feasibility and effectiveness of this organization and retrieval approach.
