Mosaic-guided Video Retargeting for Video Adaptation
نویسندگان
چکیده
Video retargeting from a full-resolution video to a lower-resolution display will inevitably cause information loss. Content-aware video retargeting techniques have been studied to avoid critical visual information loss while resizing a video. In this paper, we propose a mosaic-guided video retargeting scheme to ensure good spatio-temporal coherence of the downscaled video. Besides, a rate-distortion optimization framework is proposed to maximize the information retained in the downscaled video.

Content-Aware Retargeting For Soccer Video Adaptation
A content-aware retargeting method is proposed for adapting soccer video to heterogeneous terminals. According to domain-specific knowledge, ball, player and player’s face are defined as user interested objects (UIOs) in different view-types. The UIOs are extracted by semantic analysis on soccer video, and then a region of interest (ROI) of each shot is determined jointly by three factors: term...
متن کاملHow to Measure the Relevance of a Retargeting Approach?
Most cell phones today can receive and display video content. Nonetheless, we are still signi cantly behind the point where premium made for mobile content is mainstream, largely available, and a ordable. Signi cant issues must be overcome. The small screen size is one of them. Indeed, the direct transfer of conventional contents (i.e. not speci cally shot for mobile devices) will provide a vid...
متن کاملArt Directable Retargeting for Streaming Video
We present a novel framework for content-aware and art-directable video retargeting. A simple and interactive workflow combines key frame based constraint editing with numerous automatic algorithms for video analysis. This combination gives content producers high level control of the retargeting process. The central component of our framework is a non-uniform, pixelaccurate warp to the target r...
متن کاملAdaptation of Images and Videos for Different Screen Sizes
With the increasing popularity of smartphones and similar mobile devices, the demand for media to consume on the go rises. As most images and videos today are captured with HD or even higher resolutions, there is a need to adapt them in a content-aware fashion before they can be watched comfortably on screens with small sizes and varying aspect ratios. This process is called retargeting. Most d...
متن کاملFeature Based Image Sequence Retargeting in the Uncompressed Video Domain
The system propose a video retargeting algorithm to resize images based on the extracted saliency information from the compressed domain. The system utilizes DCT coefficients in JP2 bit stream to perform saliency detection with the consideration of the human visual sensitivity. Valuable retargeting requires emphasize the main satisfied while retain immediate context with minimal visual deformat...
