Proxy-Based Visual Content Repurposing Using Selection Algorithm

摘要

This paper presents a proxy-based visual content repurposing approach, which is used to repurpose visual content dynamically for the transmission over heterogeneous networks and end devices. We use a series of repurposing proxies in a chain fashion between the server and multiple client devices. In order to find the appropriate chain of repurposing services that maximizes the user驴s satisfaction with the delivered content, we propose a novel service selection algorithm based on user''s satisfaction with the quality of the repurposed content which is used as an optimization metric for the repurposing service selection and configuration process. Experimental results show that our approach performs complicated repurposing tasks by breaking them into a series of intermediate tasks and executing them in distributed repurposing proxies with minimal degradation of the final delivered content quality in terms of PSNR.
