报告人单位：Dublin City University，Irish
In this talk I will first give an overview of the research of the Insight Centre for Data Analytics in the areas of machine learning, computer vision, and multimedia content-based retrieval. I will choose “Smart Cities” as an example of one application domain where we apply the results of our basic research into Deep Learning for computer vision. I will provide an overview of the Smart City testbed we have established in Dublin in collaboration with Intel, Microsoft and that uses Croke Park, the 3rd largest stadium in Europe as a microcosm of a smart city environment. I explain how this stimulated a multi-track research programme in understanding the behavior of crowd from CCTV video sources. I will then present a detailed example of research in this domain where we have achieved state of the art performance. Specifically, I will present the topic of our recent IEEE CVPR paper where we propose a technique to adapt a convolutional neural network (CNN) based object counter to additional visual domains and object types while still preserving the original counting function. Domain-specific normalization and scaling operators are trained to allow the model to adjust to the statistical distributions of the various visual domains. The developed adaptation technique is used to produce a singular patch-based counting regressor capable of counting various object types including people, vehicles, wildlife and even cell nuclei in medical images.
