چکیده
The widespread usage of internet, limited bandwidth of networks and different types of media all around the net causes a vast growth in compressing data with differentabilities and qualities. Nowadays, video is a popular media for everyday usage. In different research areas, there is a need forrecording events in high frame rates. Due to the high frame rate video constraints, using complex methods are not suitable for real-time coding of these videos and will increase the cost of the system. There are different lossless, lossy and near-lossless methods for compressing video sequences. Existing lossy methodscannot limit the subjective or objective loss to a certain upper bound. There have been works regarding lossless compression ofthese sequences, however these works offer modest compression ratios and in some cases will not be enough due to the large sizeof these sequences. In this paper we propose a near-lossless method that is comparable with successful existing methods of video compression and yet is simple enough for real-time applications. It includes the major conventional parts for this goal which are prediction, quantization and entropy coding. Asimple rate control is embedded by different approaches in quantization. The experimental results demonstrate good compression ratios while considering reliability due to control of the maximum pixel errorکلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
