Depth-Image-Based Rendering (DIBR) can synthesize a virtual view image from set of multiview images and corresponding depth maps. However, this requires an accurate map estimation that incurs high compu- tational cost over several minutes per frame in DERS (MPEG-I’s Depth Estimation Reference Software) even by using high-class computer. LiDAR cameras thus be alternative solution to real-time DI...
ATM network is a flexible environment to provide efficient transport of multimedia traffic. MPEG-encoded video information constitutes significant amount of transmitted data in broadband network. The paper investigates a gain which can be obtained when using results of statistical studies on stored MPEG files. Performance of transfer of MPEG information via CBR and rt-VBR links is studied.
The MPEG-7 standard provides description mechanisms and taxonomy management for multimedia documents. There are several approaches to design a multimedia database system using MPEG-7 descriptors. We discuss two of them: relational databases and native XML databases. We have implemented a search and retrieval application for MPEG-7 descriptions based on the latter.
The ongoing MPEG-7 standard intends to provide a “Multimedia Content Description Interface.” In other words, it will provide a rich set of tools to describe content with a view to facilitating applications such as content based querying, browsing and searching of multimedia content. The MPEG-4 standard provides tools for compressing multimedia content at bitrates that are feasible with typical ...
Introduction MiR-135a is found to selectively induce apoptosis in glioma cell but not in normal neurons and glial cells. However, low transfection efficacy limits its application in vivo as other miRNAs. We prepared a new kind of nano-vector based on polyethylene glycol methyl ether (mPEG) and hyper-branched polyethylenimine (hy-PEI) in order to improve the miRNA delivery system into the glioma...
