A Web Service for Video Smart-Cropping

This paper presents a Web service that supports the automatic transformation of a video's aspect ratio. We employ a modified smart-cropping technique from the literature that aims to minimize the loss of semantically important visual content. We integrate this method in an easy-to-use publicly- accessible Web service where a video can be uploaded and automatically transformed to the desired aspect ratio. We also demonstrate that the algorithmic modifications we introduced in the process of building our Web service offer performance gains, when compared to the original method of the literature.
