Applications to Annotation and Retrieval

January 15, 2015 at 4:00 pm by

The role of text and language in solving computer vision problems, has received lots of attention in the recent past. In this talk, we present some of our attempts in bridging the textual and visual descriptions of the
world. By exploiting the relationships between textual and visual descriptions, we are able to build superior solutions for annotation  and retrieval of images and videos. We believe that to solve many immediate vision problems, one can avoid an explicit recognition and use the noisy and loosely connected descriptions.

In general, our methods attempt to align text and images which are either domain specific or even obtained from the wild. Our alignment methods use some level of supervision. We demonstrate this alignment at multiple granularity of text i.e., words, phrases and sentences. In each of these cases, alignment is formulated as an optimization/learning problem and solved with the help of data, and domain knowledge if applicable.
