Resumen
Video-based interactive storytelling has as its main goal the generation of interactive narratives,
allowing users to control the course of the story and using cinematographic compositions
to dramatize it. For this process to be possible, there is a need for large amounts of cinematographic
content in the form of filmed scenes. This content, on the other hand, has to be properly
pre-processed in order to be usable. This work proposes an approach for video segmentation
aimed for video-based interactive storytelling, using alpha matting to extract color and transparency
of video elements to be later recomposed for dramatization purposes. The developed
solution uses background subtraction and energy minimization techniques to automatically generate
trimaps.
