Visual data is becoming an integral part of society. For the general public visual data and its sharing through social media has become a way of living and is leading to a new digital culture. Scientists use cameras to record observations as source for scientific discoveries. Criminals have embraced the Internet to distribute illegal and disturbing content. Visual collections and their contextual data potentially contain a wealth of information which can range from scientific discoveries, image demographics, trends, or preferences, to forensic evidence and intelligence. Automatic algorithms are inferior to the human capabilities of identifying visual semantics or subtle patterns. Yet image collections are too voluminous to be processed by humans.

The research in Multimedia Analytics is focussed on the integration of Multimedia Analysis, Multimedia Mining, Information Visualization, and Multimedia Interaction into a coherent framework which yields more than its constituent components. Over the years main application areas are semantic video search engines, forensics, and cultural heritage. A new field is in the area of marketing within my part-time affiliation with the Amsterdam Business School (ABS).
