Rate-distortion and complexity optimized motion estimation for H.264 video coding
(IEEE-INST Electrical Electronics Engineers Inc, 2008-02)
11.264 video coding standard supports several inter-prediction coding modes that use macroblock (MB) partitions with variable block sizes. Rate-distortion (R-D) optimal selection of both the motion vectors (MVs) and the ...
Investment in improved inventory accuracy in a decentralized supply chain
(Elsevier Science BV, 2008-06)
It is known that inaccurate inventory records can lead to profit losses in a supply chain. Inventory records may not be correct due to various reasons such as transaction errors, misplacement, shrinkage, etc. In order to ...
On the spectral correlation of UWB impulse radio signals
(IEEE-INST Electrical Electronics Engineers Inc, 2008-10)
Cyclostationarity is an inherent characteristic of many communication signals, which can be exploited for performing various signal processing tasks. Determining the cyclic statistics of a signal of interest is often ...
Integration of 2D CMUT arrays with front-end electronics for volumetric ultrasound imaging
(IEEE-INST Electrical Electronics Engineers Inc, 2008-02)
For three-dimensional (3D) ultrasound imaging, connecting elements of a two-dimensional (2D) transducer array to the imaging system's front-end electronics is a challenge because of the large number of array elements and ...
Comment on "Encryption and decryption of images with chaotic map lattices" [Chaos 16, 033118 (2006)]
(American Institute of Physics Inc., 2008-09)
In this paper, we comment on the chaotic encryption algorithm proposed by A. N. Pisarchik et al. [Chaos 16, 033118 (2006)]. We demonstrate that the algorithm is not invertible. We suggest simple modifications that can ...
Spectral coding of mesh geometry with a hierarchical set partitioning algorithm
(Spie-Int Soc Optical Engineering, 2008)
This work proposes a progressive mesh geometry coder, which expresses geometry information in terms of spectral coefficients obtained through a transformation and codes these coefficients using a hierarchical set partitioning ...
Üç boyutlu göz geometrisinin küme bölüntüleme ile verimli spektral kodlaması
(Tübitak, 2008-08)
3-B nesnelerin görselleştirilmesi uygulamalarında kullanılan tel filelerin ( gözlerin) geometrilerinin sıkıştırılması (DEERİNG, 1995)’deki ön görücü kodlamaya dayanan yöntem ile beraber rağbet gören bir araştırma alanı ...
A cost-efficient bit-serial architecture for sub-pixel motion estimation of H.264/AVC
(IEEE Computer Soc, 2008)
This paper presents a new VLSI architecture for sub-pixel motion estimation in H.264/AVC encoder. It is based on an interpolation free algorithm that causes a high level reduction on memory requirement, hardware resources ...
