The Conference on Design and Architectures for Signal and Image Processing DASIP addresses the development of complex applications involving signal, image and control processing based on a new approach called Algorithm-Architecture-Matching, which aims to leverage the design flow by a simultaneous study of both algorithmic and architectural issues, taking into account multiple design constraints, as well as algorithm and architecture optimizations. The goal of DASIP is to present the latest results in the domain of design and architecture for signal and image processing along several axes: methods and tools; development platforms, architectures and technologies; use-cases and applications as well as smart sensing systems. The 7th annual DASIP Conference will be organized in Cagliari, Italy, capital of the beautiful island of Sardinia. The Conference includes keynote speeches, contributed paper sessions, poster sessions, and special sessions on timely topics. This year features four Special Sessions with the purpose of introducing the DASIP community to relevant hot topics that were not covered by previous editions of the conference.
