The objective of this proposal, entitled `Intelligent signal processing for future DIgital MEdia Systems', (I-DIMES) is to research promising ideas in the design, development and application of intelligent signal processing solutions that provide cognitive processing of digital content, model and analyze complex human behaviour, and facilitate autonomous recognition of context in a process-centric digital environment. This program attempts to provide answers to three interlaced problems, namely: (a) attention problem - how to extract the relevant digital information; (b) interface problem - what is the best way to present the information when the conditions have changed; and (c) application problem - what are the best uses for the extracted information. Thus, the long term research objectives of this proposal are to: (i) provide a comprehensive and systematic study of the links between digital content, context learning, situation awareness, activity recognition, and adaptation; (ii) devise a generalized processing framework for activity and behaviour recognition as part of a digital media environment. The short term objectives are to: (i) personalize access to visual content using end-users' preferences and profiles; (ii) organize content in order to enhance processing, retrieval, coding, and transmission of visual content; (iii) empower users through content and context fusion; (iv) introduce an integrity preservation and privacy enhancing framework; and (v) exploit novel applications of the developed solutions. In addition to having significant theoretical implications, the proposed research program has potential for social impact through the development of technological solutions for enhancing the life of individuals. To this end, an application scenario has been chosen to test the applicability of the proposed methodologies. The scenario comes from the field of EEG-based brain-computer interfaces and it will be used to test user-intention inference and cognitive processing recognition procedures.

这项题为“未来数字媒体系统的智能信号处理”（I-DIMES）的提案的目的是研究智能信号处理解决方案的设计、开发和应用方面的有前途的想法，这些解决方案提供数字内容的认知处理，建模和分析复杂的人类行为，并促进以过程为中心的数字环境中的上下文自主识别。本节目试图回答三个交错的问题，即：（a）注意力问题-如何提取相关的数字信息;（B）接口问题-当条件发生变化时，什么是呈现信息的最佳方式;（c）应用问题-提取的信息的最佳用途是什么。因此，这项建议的长期研究目标是：（一）提供一个全面和系统的研究数字内容之间的联系，上下文学习，态势感知，活动识别和适应;（二）设计一个通用的处理框架的活动和行为识别的一部分，数字媒体环境。短期目标是：（一）利用最终用户的偏好和配置文件对视觉内容进行个性化访问;（二）组织内容，以增强视觉内容的处理、检索、编码和传输;（三）通过内容和上下文融合赋予用户权力;（四）引入完整性保护和隐私增强框架;以及（五）利用所开发解决方案的新应用。除了具有重要的理论意义外，拟议的研究计划还具有通过开发技术解决方案来改善个人生活的社会影响潜力。为此，一个应用场景已被选择来测试所提出的方法的适用性。该场景来自基于EEG的脑机接口领域，它将用于测试用户意图推理和认知处理识别程序。
