Problem : As of the time this paper was published, there was a need to prove the contribution of context information for object detection tasks.
Solution : This paper integrated the top performing detector with context aware approaches and also presented a few novel approaches using geographic contextand spatial information.
Comment : The abstact did not clearly explain the novel approaches.
First thought on the paper.
The title of the paper is a little bit abstract and has too broad coverage, which means this paper is a earlier work in this topic.
What is object detection ? Is it object detection deep learning model or does it mean simply the concept "object detection" ? I think in this case, it is latter one.
And the solution might be obtained by a experimental result not a mathemetical approach.
