There is a need for automatic processing and extracting of meaningful metadata from multimedia information,udespecially in the audiovisual industry. This higher level information is used in a variety of practices, such as enrichingudmultimedia content with external links, clickable objects and useful related information in general. This paper presents a system for efficient multimedia content analysis and automatic annotation within a multimedia processing and publishing framework. This system is comprised of three modules: the first provides detection of faces and recognition of known persons; the second provides generic object detection, based on a deep convolutional neural network topology; the third provides automated location estimation and landmark recognition based on state-of-the-art technologies. The results are exported in meaningful metadata that can be utilized in various ways. The system has been successfully tested in the framework of the EC Horizon 2020 Mecanex project, targeting advertising and production markets.
