英文摘要： Cloud computing, with its powerful capability of computing and storage and with its large-scale data resource, provides unprecedented opportunities for IT industry. However, as an emerging computing infrastructure, various heterogeneities in services, devices, networks, plus the requirements of instantaneous responses to the bursts of simultaneous large-scale data access and processing, bring about great challenges to the cloud-based multimedia applications and services. How to support complex and even unpredictable multimedia services as well as manipulate large scale data at the same time to provide good quality of experience (QoE), becomes one of the crucial and fundamental problems for cloud-based multimedia processing. This proposed project includes two main research issues: 1) cloud-based video intelligent processing technology; and 2) cloud-aware video representation and coding method. For the sake of breaking the tight coupling between multimedia processing and application, we propose in this project: 1) to investigate multimedia intelligent processing method based on latent machine learning (LML) and latent data mining (LDM), which is able to achieve scalable recognition; 2) to develop a type of cloud-aware video representation, dubbed Intermedia, based on which the fast generation of scalable video cod
