A Robust Superimposed Caption Box Content Understanding for Sports Videos

This paper proposes a semantics understanding system to interpret the superimposed caption box (SCB) in sports videos of which the template of SCB is presumably not a priori. The semantics in SCB represent the digested key information of the sports video content. Most of the previous studies assume that the SCB template is known as a priori, and require the representative character bitmaps. The SCB understanding system consists of SCB extraction, character extraction, digit/text character recognition, digital object interpretation using labeling mechanism. In the experiments, we will illustrate that the system can interpret the SCB in basketball and baseball game videos successfully
