Visual Question Answering - Wu, Qi

. .

Résumé :
Visual Question Answering (VQA) usually combines visual inputs like image and video with a natural language question concerning the input and generates a natural language answer as the output. This is by nature a multi-disciplinary research problem, involving computer vision (CV), natural language processing (NLP), knowledge representation and reasoning (KR), etc. Further, VQA is an ambitious undertaking, as it must overcome the challenges of general image understanding and the question-answering task, as well as the difficulties entailed by using large-scale databases with mixed-quality inputs. However, with the advent of deep learning (DL) and driven by the existence of advanced techniques in both CV and NLP and the availability of relevant large-scale datasets, we have recently seen enormous strides in VQA, with more systems and promising results emerging. This book provides a comprehensive overview of VQA, covering fundamental theories, models, datasets, andpromising future directions. Given its scope, it can be used as a textbook on computer vision and natural language processing, especially for researchers and students in the area of visual question answering. It also highlights the key models used in VQA....

Biographie:
Dr. Qi Wu is Senior Lecturer at the University of Adelaide and Chief Investigator at the ARC Centre of Excellence for Robotic Vision. He is also Director of Vision-and-Language Methods at the Australian Institute for Machine Learning. Dr Wu has been in the Computer Vision field for 10 years and he has a strong track record, having pioneered the field of Vision-and-Language, one of the most interesting and technically challenging areas of Computer Vision. This area, which has emerged over the last 5 years, represents the application of computer vision technology to problems that are closer to Artificial Intelligence. Dr Wu has made breakthroughs in methods and conceptual understanding to advance the field and is recognised as an international leader in the discipline. Beyond publishing some of the seminal papers in the area, he has organised a series of workshops in CVPR, ICCV and ACL. and authored key benchmarks that define the field. Recently, he led a team that won second place in VATEX Video Captioning Challenge, the first place in both TextVQA Challenge and MedicalVQA Challenge. His achievements have been recognised with the Australian Academy of Science J G Russel Award in 2019, one of four awards to ECRs across Australia...
