This paper presents an overview of the video compression standards related to the MPEG family. MPEG-7 and MPEG-21 are specially covered including its latest standard. MPEG-7 is mainly used for object descriptions and MPEG-21 is for DRM (Digital Rights Management). Keyword: MPEG-1, MPEG-2, MPEG-4, MPEG-7, MPEG-21, MPEG-A, MPEG-D I.INTRODUCTION MPEG is the “Moving Picture Experts Group”, working ...

This paper demonstrates that it is possible to produce automatic, reconfigurable, and portable implementations of multimedia decoders onto platforms with the help of the MPEG Reconfigurable Video Coding (RVC) standard. MPEG RVC is a new formalism standardized by the MPEG consortium used to specify multimedia decoders. It produces visual representations of decoder reference software, with the he...

Combination chemotherapy is an important protocol in glioma therapy and honokiol shows synergistic anticancer effects with doxorubicin. In this paper, honokiol (HK) and doxorubicin (Dox) co-loaded Methoxy poly(ethylene glycol)-poly(ε-caprolactone) (MPEG-PCL) nanoparticles were prepared with a assembly method. The particle size (about 34 nm), morphology, X-ray Powder Diffraction (XRD), in vitro ...

Intravesical application of an anti-inflammatory drug is an efficient strategy for acute cystitis therapy. Quercetin (QU) is a potent anti-inflammatory agent; however, its poor water solubility restricts its clinical application. In an attempt to improve water solubility of QU, biodegradable monomethoxy poly(ethylene glycol)-poly(ɛ-caprolactone) (MPEG-PCL) micelles were used to encapsulate QU b...

From multimedia history, we can see that however powerful the technologies underlying multimedia systems, only relevant authoring applications will bring success to these systems. From this assumption MPEG-Pro, a first MPEG-4 authoring system prototype has been designed to integrate all main authoring capabilities from Audio/Visual encoding to the final delivery of a complete MPEG-4 application...

MPEG-4 Body Animation Parameters (BAPs) are used for animation of MPEG-4 compliant virtual human-like characters. Distributed virtual reality applications and networked games on mobile computers require access to locally stored or streamed compressed BAP data. Existing MPEG-4 BAP compression techniques are inefficient for streaming, or storing, BAP data on mobile computers, because (a) MPEG-4 c...

A programmable processor architecture for MPEG-4 video is proposed, that can serve as a coprocessor module in MPEG-4 decoder systems. It consists of a 64-bit dual-issue VLIW macroblock engine, a separate RISC core for bitstream parsing and system processing, and an autonomous I/O processor. A separate DSP is used for MPEG audio support. The architecture is fully programmable and supports parall...

Curcumin (Cur), a natural polyphenol of Curcuma longa, has been recently reported to possess antitumor activities. However, due to its poor aqueous solubility and low biological availability, the clinical application of Cur is quite limited. The encapsulation of hydrophobic drugs into nanoparticles is an effective way to improve their pharmaceutical activities. In this research, nanomicelles lo...

Amphiphilic block copolymers have attracted a great deal of attention in drug delivery systems. In this work, a series of monomethoxy-poly (ethylene glycol)-poly (ε-caprolactone-co-D,L-lactide) (MPEG-PCLA) copolymers with variable composition of poly (ε-caprolactone) (PCL) and poly (D,L-lactide) (PDLLA) were prepared via ring-opening copolymerization of ε-CL and D,L-LA in the presence of MPEG a...

در این پایان نامه به مبحث پردازش در حوزه فشرده می پردازیم و با استفاده از آن الگوریتمی برای وارد کردن لوگو در حوزه فشرده سیگنال ویدئوئی mpeg پیشنهاد می کنیم. پردازش روی تصاویر ساکن و متحرک را می توان پس از دیکد کردن آنها و در حوزه مکان انجام داد. ولی انجام مستقیم پردازش در حوزه فشرده، با حذف مراحل دیکد کردن و کدکردن مجدد باعث افزایش سرعت و کاهش پیچیدگی می شود. آشنایی با پردازش در حوزه فشرده مست...
