methoxy poly(ethylene glycol) (mpeg) with molecular mass of 5 kda activated with succinimidyl carbonate and cyanuric chloride, separately was covalently attached to human red blood cells (rbcs). inhibition of agglutination by blood-type specific antisera (anti-d) was employed to evaluate the effect of the polymer coating. the remaining single cells after incubation with anti-d sera were counted...
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...
This article introduces the ISO/IEC MPEG Immersive Video (MIV) standard, MPEG-I Part 12, which is undergoing standardization. The draft MIV standard provides support for viewing immersive volumetric content captured by multiple cameras with six degrees of freedom (6DoF) within a space that determined camera arrangement in capture rig. bitstream format and decoding processes specification along ...
The MPEG Encoded Retrieval and Indexation Toolkit (MERIT) performs video segmen-tation of MPEG les in the compressed domain, using an algorithm based on macroblock type statistics. It was written in C by V. Kobla in 1995 for his doctoral work at the University of Maryland. Kobla's code dealt with MPEG-1 les only. In this report we update MERIT to analyze MPEG-2 les as well. We modify the le par...
Both folic acid (FA)- and methoxypoly(ethylene glycol) (mPEG)-conjugated chitosan nanoparticles (NPs) had been designed for targeted and prolong anticancer drug delivery system. The chitosan NPs were prepared with combination of ionic gelation and chemical cross-linking method, followed by conjugation with both FA and mPEG, respectively. FA-mPEG-NPs were compared with either NPs or mPEG-/FA-NPs...
The paper deals with efficient compression of immersive video representations for the synthesis relatedto virtual viewports, i.e., to selected viewer positions and directions watching. Thegoal is obtain possibly high quality obtained from compressed immersivevideo acquired multiple omnidirectional planar (perspective) cameras, or computer animation. Inthe paper, we describe a solution based on ...
This paper gives an overview of Part 1 of ISO/IEC 15939 (MPEG-7 Systems). It first presents the objectives of the MPEG-7 Systems activity. In the MPEG-1 and MPEG-2 standards, “Systems” referred only to overall architecture, multiplexing, and synchronization. In MPEG-4, in addition to these issues, the Systems part encompasses interactive scene description, content description, and programmabili...
