To investigate the impact of buffer on stereoscopic video coding, three rate control (RC) methods were presented. In the separate buffer RC method (SBRC), left and right views achieved rate controlling using respective buffer in their own given target bitrates. The united buffer RC (UBRC) and its improved united buffer RC (I-UBRC) methods were both in a given total bandwidth and the united buff...

Inspired by the pioneering work in photographic studies of motion and motion picture projection by Eadweard Muybridge in 1878 and by the high speed films of Harold Edgerton by the middle of the 20th century, the use of video has rapidly emerged nowadays as a powerful tool to teach physics at schools and universities, capturing what the human eye could not distinguish. To highlight the advantage...

In this paper we describe audio and video processing algorithms that are developed in the scope of AVATecH project. The purpose of these algorithms is to shorten the time taken by manual annotation of audio and video recordings by extracting features from media files and creating semi-automated annotations. We show that the use of such supporting algorithms can shorten the annotation time to 30...

In this paper, we address the problem of allocating bits among pictures in an MPEG video coder to equalize the visual quality of the coded pictures, while meeting buffer and channel constraints imposed by a Video Buffer Verifier. We address this problem within a framework consisting of 1) a bit production model for the input pictures, 2) a novel lexicographic criterion for optimality, and 3) a ...

We propose a novel capture and annotation system called TagTansu, which can easily capture pictures of clothes and add annotations to support creating a picture database of clothes. TagTansu consists of hook sensors and capture components attached inside the doors of a tansu (a wardrobe).Using TagTansu, users can easily take pictures of clothes and add annotations (e.g. types and weight of clot...

Traditional event models couldn’t model temporal-spatial information very well in narrative image tagging task especially in the field of culture heritage. In this paper, we design a narrative image annotation ontology (NIAO) model and tool (NIA) to address this issue by using ontology design patterns and other related vocabularies for reusability. The annotation model, combining with OAC (Open...

The rapidly increasing quantity of publicly available videos has driven research into developing automatic tools for indexing, rating, searching and retrieval. Textual semantic representations, such as tagging, labelling and annotation, are often important factors in the process of indexing any video, because of their user-friendly way of representing the semantics appropriate for search and re...
