چکیده

Abstract. In this work we present a transcoding framework and an object-based technique to adapt live and stored videos to the user bandwidth and resources capabilities. Multiple transcoding policies are reviewed and a performance evaluation metric based on the Weighted Mean Square Error that allows different classes of relevance is presented. We present results for different transcoding policies and for different bandwidth requirements, showing that the use of semantic can improve the bandwidth to distortion ratio.

Semantic Video Transcoding Using Classes of Relevance

In this work we present a framework for on-the-fly video transcoding that exploits computer vision-based techniques to adapt the Web access to the user requirements. The proposed transcoding approach aims at coping both with user bandwidth and resources capabilities, and with user interests in the video’s content. We propose an object-based semantic transcoding that, according to user-defined c...

Semantic transcoding of video based on regions of interest

Traditional transcoding on multimedia has been performed from the perspectives of user terminal capabilities such as display sizes and decoding processing power, and network resources such as available network bandwidth and quality of services (QoS) etc. The adaptation (or transcoding) of multimedia contents to given such constraints has been made by frame dropping and resizing of audiovisual, ...

Object and event detection for semantic annotation and transcoding

Video annotation provides a suitable way to describe, organize, and index stored videos. On the other hand, transcoding aims at adapting content to the user/client capabilities and requirements. Both cues are now mandatory, given the tremendous demand of multimedia access from remote clients, in particular nowadays that new terminals with limited resources (PDAs, HCCs, Smart phones) have access...

A framework for video representation and transcoding using appearance spaces

We present a novel scheme for object-based video sequence representation using appearance spaces. Our scheme enables fully automatic extraction of semantic video objects for a class of sequences, and their supervised organization in an object-class hierarchy. The hierarchy can be used for generic classification of query video objects, and transcoding using semantics of video objects.

Semantic segmentation and description for video transcoding

We present an automatic content-based video transcoding algorithm which is based on how humans perceive visual information. The transcoder support multiple video objects and their description. First the video is decomposed into meaningful objects through semantic segmentation. Then the transcoder adapts its behaviour to code relevant (foreground) and non relevant objects differently. Both objec...
