Title: Generation of Natural Language Descriptions for Images

Abstract:

Generation of human-like and relevant descriptions for images is a challenging
task. We present an approach for collective generation of natural image
descriptions. Our method exploits preexisting human written captions in order to
obtain plausible output. We cast the generation process as an Integer Linear
Programming (ILP) task. The proposed ILP formulation combines parts of the
associated preexisting captions into a new description for the target image.

However, extraneous information present in human text can hurt the relevance of
the generated descriptions. Thus, we introduce a new task of image caption
generalization. We exploit Dynamic Programming (DP) to remove information which
is less likely to be visually verifiable. In order to filter grammatically
incorrect solutions we enhance DP with typed dependency constraints. Resulting
generalized captions are potentially more applicable to the generation of image
descriptions.
