Paper 226: Camera-based sensory substitution and augmented reality for the blind
Rapid developments in mobile computing and sensing with smartphones open up new opportunities for augmenting our reality with information and experiences that our senses could not directly provide. One current trend is towards augmented reality applications based on location-based services (LBS) and computer vision. Apart from mass-market uses, there also arise new uses in niche markets such as technology for the blind.
Despite its more limited commercial value, I will in my talk discuss how this particular niche market is extremely interesting for bringing together research on man-machine interfaces, computer vision, brain plasticity, synesthesia, and even contemporary philosophy. It is also an area where fundamental research (e.g. on brain plasticity) may prove directly socially relevant through applications that are readily made globally available over the web, and that run on mass-market devices.
Hybrid applications convey via sound or touch the raw visual information from live camera views as well as semantic information for nearby items of interest, as recognized through computer vision or identified through location databases. Moreover, neuroscience research has in the past decade established that the visual cortex of blind people becomes responsive to sound and touch, thus adding some biological plausibility to the idea of creating non-invasive sensory by-passes in the form of sensory substitution.
Paper 227: Distributed Smart Cameras for Health and Wellbeing
With the increasing elderly population there is a growing interest in systems that are able to monitor the activities of elderly and to use the information for coaching or for alarming. In this way people are able to live independently in their homes for a longer period of time. I will give an overview of the types of activities that are relevant for monitoring, and how cameras can be used for these applications. In this context I will present our work on fall detection with different camera systems. Apart from alarm functions, cameras are also used for therapies and gaming. I will present some of our work in this field. Finally I will present some of our work that studies privacy issues related to camera monitoring.
Paper 228: The tale of 1000 cameras
More and more cameras are appearing in public areas. Such cameras are mostly collecting images for later inspection and provide little more. The presentation discusses what keeps us from exploiting them in more intelligent ways for collaboration. We will look within cameras with multiple vision sensors, and within intelligent mobile networks. From there, we will outline the 1000 camera project for quality control on factory lines.
Paper 229: Computers Seeing Humans --- Vision-based Perception of Humans for Smart Environments and Other Applications
Vision-based perception of humans has a wide range of applications ranging from building human-friendly technical systems such as human-friendly robots or smart environments to applications in surveillance and image retrieval. In this talk I will present some of our recent efforts towards building such systems. In particular I will talk about an ongoing smart control room project, where our aim is to build an attentive smart room to support crisis control work. In this room, real-time perception of people is used to enable personalized workspace that follow people in the room, and to allow gesture and gaze based interaction with large displays and across devices in the room. I will also talk about some ongoing efforts in person identification and retrieval in multimedia data and camera networks. Finally, I will mention some commercial uses cases of such technology such as video-based customer monitoring, including age and gender recognition.
Paper 230: Optical Issues in the Paintings of Jan Van Eyck
The major decade in the artistic life of Jan Van Eyck (+/-1390-1441) was the decade in which linear perspective was codified as the backbone of the art of painting by Leon Battista Alberti in De pictura (1435). According to the archival research of art historian Hugo van der Velden of Harvard University, the completely assembled Ghent Altarpiece, by far the largest work of the Van Eyck's, came about in the very same year (and not in 1432 as currently indicated on the frame). Art historians have valued Jan Van Eyck for what seems painstaking realism in depicting materials but they have deplored his failure to adopt the strict rules of linear perspective. In the talk Marc De Mey will highlight some of the clever tricks and ingenious devices of Jan Van Eyck which indicate advanced optical understanding complementary and even superior to Albertian perspective. The talk will be illustrated with materials and macro photographs in a powerpoint presentation based on the digitized Dierick collection of high quality photographic negatives made available to Ghent University by the family of the late father Alfons Dierick.
