Determining Commonalities in Crowd Sourced Data

Prof. Subhasis Chaudhuri
Department of Electrical Engineering
Indian Institute of Technology Bombay
Powai, Mumbai 400 076, India

Abstract:

When several observers capture images or videos at different times and locations, is there a common object of interest? If there is, can we process these images to identify the common object(s) in these scenes? This problem is known as image co-segmentation. In the first part of the talk, we discuss how this task can be achieved. Quite naturally, the computation goes up as the number of observations increases albeit the size of the common object is a non-increasing function of the number of observations. However, if these crowd sourced observations are taken at the same geographic region and at the same time with smart-phones, as is the norm of the day, the associated meta-data can be used very efficiently to geo-locate the common object and to estimate the salient view of each observer, following which computer vision-based techniques can be used to carve out the common object in space and time. The second part of the talk will focus on the use of meta data.
