Sprite Aided Video Compression and Segmentation
ثبت نشده
چکیده
With the rapid developments on multimedia and Internet, more and more images and videos are transmitted and viewed in digital form. Video representation and compression are at the foundation of such kind of multimedia applications. Object-based video coding, also known as the representatives of content-based video coding, has been proposed to represent and compress the foreground and the background separately, which aims at not only achieving high coding efficiency but offering many desired functionalities that never exist in frame-based coding schemes. Accordingly, one of the main problems of object-based video coding arises from how to efficiently compress the video objects represented with different motions. A further main problem of object-based video coding arises from how to segment the video into meaningful regions, i.e. the background and the foreground.

Sprite-based video coding using on-line segmentation
We address the problem of on-line sprite-based video coding in cases where scene segmentation is not available a priori or transmission of such segmentation information cannot be afforded due to low bit rate requirements. We propose an on-line segmentation method that can be integrated into an MPEG4 online sprite based video codec. The proposed method uses macroblock types as well as motion com...
متن کاملEfficient background video coding with static sprite generation and arbitrary-shape spatial prediction techniques
In this paper, an efficient static sprite-generation and compression scheme is proposed for background video coding. First, considering both shortand long-term motion influences, a hybrid technique is proposed in the sprite generation to search the background motion relative to the generated sprite image. In order to prevent the sprite image from being blurred due to the inaccurate segmentation...
متن کاملSprite generation for frame-based video coding
Sprite coding is a very efficient method for the representation and compression of background video object, which has been accepted by MPEG-4 standard. However, how to automatically generate sprite image from raw video sequence is still an open issue, because the motion of foreground video objects not only disturbs the accuracy of motion estimation but also blurs the generated sprite image. Thi...
متن کاملFast and Robust Sprite Generation for MPEG-4 Video Coding
This paper presents a fast and robust sprite generation algorithm for MPEG-4 video coding. Our contributions consist of two aspects. Firstly, a fast and robust Global Motion Estimation (GME) algorithm is proposed here. Spatial and temporal feature point selection schemes are incorporated into the hierarchical GME in order to speed up it. Experimental results demonstrate our method is up to seve...
متن کاملPopescu Compact Real - Time Modeling of Seated Humans by Video Sprite Sequence
We propose an image-based method for real-time modeling of seated humans using upper-body video sprites, which is suitable for applications such as teleconferencing and distance learning. A database of representative video sprite sequences is pre-acquired and pre-uploaded to each remote rendering site. At run time, for each input sprite, a closely matching sprite is located in the database and ...
