H.264 vi?deo kodlamada B-çerçeveler i?çi?n kodçözücü tarafında aday devi?ni?m vektör seçi?mi?
(IEEE, 2012-04-18)
H.264 standardında devinim vektör farklarının kodlanması sebebiyle özellikle düşük bit hızlarında nesne sınırlarında devinimdeki ani değişiklikler harcanan bit miktarlarını artırmaktadır. Bu bildiride B-çerçevelerde kod ...
Enhanced low bitrate H.264 video coding using decoder-side super-resolution and frame interpolation
(SPIE-SOC Photo-Optical Instrumentation Engineers, 2013-07)
Advanced inter-prediction modes are introduced recently in literature to improve video coding performances of both H.264 and High Efficiency Video Coding standards. Decoder-side motion analysis and motion vector derivation ...
Analysis and design of low-cost bit-serial architectures for motion estimation in H.264/AVC
(Springer, 2013-05)
Variable block-size motion estimation (VBSME) process occupies a major part of computation of an H.264 encoder, which is usually accelerated by bit-parallel hardware architectures with large I/O bit width to meet real-time ...
Mülteci barınaklarının uydu görüntülerinden çoklu-sınıflı çizge-kesme bölütleme ve gölge bilgisi kullanılarak otomatik sezimi

Bu çalışmada, mülteci kamplarında bulunan yaşam
alanlarının/barınakların (çadır, konteynır vb.) uydu ve hava görüntülerinden otomatik olarak sezimi ve sayımına yönelik bir yöntem tanıtılmaktadır. Mülteci kamplarındaki ...
Fast algorithm analysis and bit-serial architecture design for sub-pixel motion estimation in H.264
(World Scientific Publishing Company, 2010-12)
The sub-pixel motion estimation (SME), together with the interpolation of reference frames, is a computationally extensive part of the H.264 encoder that increases the memory requirement 16-times for each reference frame. ...
3-D Mesh geometry compression with set partitioning in the spectral domain
(IEEE-INST Electrical Electronics Engineers Inc, 2010-02)
This paper explains the development of a highly efficient progressive 3-D mesh geometry coder based on the region adaptive transform in the spectral mesh compression method. A hierarchical set partitioning technique, ...
Hierarchical quantization indexing for wavelet and wavelet packet image coding
(Elsevier Science BV, 2010-02)
In this paper, we introduce the quantization index hierarchy, which is used for efficient coding of quantized wavelet and wavelet packet coefficients. A hierarchical classification map is defined in each wavelet subband, ...
A survey of algorithms and architectures for H.264 sub-pixel motion estimation
(World Scientific, 2012-05)
This paper reviews recent state-of-the-art H. 264 sub-pixel motion estimation (SME) algorithms and architectures. First, H.264 SME is analyzed and the impact of its functionalities on coding performance is investigated. ...
Decoder side true motion estimation for very low bitrate b-frame coding
(IEEE, 2011)
In H.264 standard, coding of motion vectors constitutes a significant portion of total bitrate especially at low bitrate regimes. This is because differential coding of motion vectors is inefficient when the bit budget is ...
Efficient quality of multimedia experience using perceptual quality metrics
(Springer-Verlag Berlin, 2016)
Although there are very few metrics which correlate well with the Human Visual System (HVS), most of them do not. We extensively studied about the Video Quality Assessment (VQA) of 2D svideos for enhancing the Quality of ...
