The field of digital signal processing (DSP) has experienced explosive growth during the past couple of decades. The DSP techniques have become integral parts of the products and services that we need or encounter in our daily lives. The research efforts of the applicant in this area during the past five years have led to some very concrete results that have been shared with the international scientific community, both from academia and industry, and have given rise to new ideas and directions that need to be further investigated. The overall objective of the proposed research program is to develop efficient algorithms and architectures and to lay sound mathematical foundations for reliable processing of image, video and biomedical signals, and cost-effective implementation for communication and biomedical applications. For half a decade now, the growth in the internet of things (IoT) and the demand for machine-to-machine connections have been staggering. By 2020, the global IP networks will have to support more than 50 billion devices. In order to establish a reliable and smooth communication among such a large number of devices connected to IoT, while still maintaining efficient and sustainable power consumption, the development of versatile, smart, fast, and real-time direction of arrival (DOA) estimation algorithms is of paramount importance. Deep learning has opened up the limitless possibilities in understanding and recognition of images. Image understanding and analysis is inherently a big data problem. Hence, the use of advanced deep learning concepts can produce meaningful results in image understanding and visual tracking, which play an important role in a wide range of real-life applications such as detection and recognition, human behavior analysis, video indexing and retrieval, medical imaging, and traffic management of smart cities. Alzheimer's disease is the most common type of dementia affecting elderly people worldwide. There is no cure for this disease, and the disease worsens as it progresses. Early detection is a key to preventing, slowing and stopping Alzheimer's disease. Around-the-clock observation of patients is expensive, inconvenient, and in some cases, simply impossible. The technology of body area networks proposes a convenient and useful solution that promises to provide physicians access to the patient's physiological data anytime and anywhere. Application of compressed sensing and statistical learning of biomedical signals can make this technology affordable. This research in the immediate future is aimed at investigating these problems and seeking their solutions by developing efficient DSP algorithms and architectures. The direct beneficiary of this research will be Canadian telecommunication and biomedical industry. This proposal will also contribute to Canadian industry and academia by enabling the training of a number of skilled personnel.

数字信号处理（DSP）领域在过去几十年中经历了爆炸式的增长。DSP技术已经成为我们日常生活中需要或遇到的产品和服务的组成部分。过去五年来，申请人在这一领域的研究工作取得了一些非常具体的成果，与国际学术界和工业界的科学界分享，并产生了新的想法和方向，需要进一步研究。拟议的研究计划的总体目标是开发高效的算法和架构，并奠定良好的数学基础，可靠的图像，视频和生物医学信号的处理，并具有成本效益的通信和生物医学应用的实施。五年来，物联网（IoT）的增长和对机器对机器连接的需求一直令人震惊。到2020年，全球IP网络将必须支持超过500亿台设备。为了在连接到物联网的大量设备之间建立可靠和流畅的通信，同时仍然保持高效和可持续的功耗，开发通用，智能，快速和实时的到达方向（DOA）估计算法至关重要。深度学习为图像的理解和识别开辟了无限的可能性。图像理解和分析本质上是一个大数据问题。因此，使用先进的深度学习概念可以在图像理解和视觉跟踪方面产生有意义的结果，这在检测和识别、人类行为分析、视频索引和检索、医学成像以及智能城市的交通管理等广泛的现实应用中发挥着重要作用。阿尔茨海默病是影响全世界老年人的最常见的痴呆症类型。这种病无药可医，而且随着病情的发展，病情会恶化。早期发现是预防、减缓和阻止阿尔茨海默病的关键。对病人进行全天候的观察是昂贵的，不方便的，在某些情况下，根本不可能。体域网技术为医生提供了一个方便、实用的解决方案，使医生能够随时随地获取病人的生理数据。生物医学信号的压缩传感和统计学习的应用可以使这项技术负担得起。这项研究在不久的将来，旨在调查这些问题，并寻求他们的解决方案，通过开发高效的DSP算法和架构。这项研究的直接受益者将是加拿大的电信和生物医学产业。该提案还将通过培训一些技术人员，为加拿大工业和学术界做出贡献。
