We present methods for semantic annotation of multimedia data. The goal is to detect semantic attributes (also referred to as concepts) in clips of video via analysis of a single keyframe or set of frames. The proposed methods integrate high performance discriminative single concept detectors in a random field model for collective multiple concept detection. Furthermore, we describe a generic f...

Marine monitoring systems have the requirements of a large field of view, low power consumption, real-time viewing, and economical and automatic functionality. This paper establishes an omnidirectional vision system used in marine buoys that meets these requirements. We present a framework for image stabilization, which is achieved by omnidirectional sea-skyline detection in a marine environmen...

We present methods for turning pair-wise registration algorithms into drift-free trackers. Such registration algorithms are abundant, but the simplest techniques for building trackers on top of them exhibit either limited tracking range or drift. Our algorithms maintain the poses associated with a number of key frames, building a view-based appearance model that is used and refined during track...

Storyboard consisting of key-frames is a popular format of video summarization as it helps in efficient indexing, browsing and partial or complete retrieval of video. In this paper, we have presented a size constrained storyboard generation scheme. Given the shots i.e. the output of the video segmentation process, the method has two major steps: extraction of appropriate key-frame(s) from each ...

The success of eLearning depends on the broad availability of educational materials that provide a high-quality delivery of high-quality content. One approach for high-quality delivery is to rely on a computer animated instructor avatar that not only speaks, but that also gestures to elucidate novel concepts and to convey an engaging personality that captures and maintains the learners’ focus. ...

Key frames are extracted to make video processing more efficient and effective. The key frames are those frames which are selected from the total frames of a video that can represent the information of whole video. Basically a video contains hundred, or thousands, or millions of frames depending upon the size and frame rate. The previous approaches have been either extracted a single frame or e...
