Spherical Coding Algorithm for Wavelet Image Compression 

Ateş, Hasan Fehmi; Orchard, Michael T. (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2009-05)
In recent literature, there exist many high-performance wavelet coders that use different spatially adaptive coding techniques in order to exploit the spatial energy compaction property of the wavelet transform. Two crucial ...

Spherical representation in wavelet packets for image coding 

Ateş, Hasan Fehmi; Tamer, Engin (IEEE, 2008)
In this paper, we present an adaptation of the spherical coder, which has been developed for wavelet transform, to wavelet packets. This coder uses local energy as a direct measure to differentiate the spatial informatin ...

Occlusion artifact removal in video frame rate up-conversion 

Çizmeci, Burak; Ateş, Hasan Fehmi (IEEE, 2009)
In the past, frame rate up-conversion (FRC) methods were commonly used in standards conversion. Today, FRC methods are used for digital video temporal resolution enhancement to improve the visual quality in large screen ...

A survey of algorithms and architectures for h.264 sub-pixel motion 

Fatemi, Mohammad Reza Hosseiny; Ateş, Hasan Fehmi; Salleh, Rosli (WORLD SCIENTIFIC PUBL CO PTE LTD, 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. ...

Enhanced low bitrate H.264 video coding using decoder-side super-resolution and frame interpolation 

Ateş, Hasan Fehmi (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 ...

Fast algorithm analysis and bit-serial architecture design for sub-pixel motion estimation in H.264 

Fatemi, Mohammad Reza Hosseiny; Ateş, Hasan Fehmi; Salleh, Rosli (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. ...

Equiripple design of real and complex filter banks 

Ateş, Hasan Fehmi; Orchard, Michael T.; Kanberoğlu, Berkay (IEEE, 2006)
A simple methodology is presented for mapping minimax-optimal, equiripple unconstrained filters such as those produced by the Parks-McClellan algorithm to design equiripple perfect-reconstruction filter banks. The method ...

Decoder-side super-resolution and frame interpolation for improved H.264 video coding 

Ateş, Hasan Fehmi (IEEE, 2013)
In literature decoder-side motion estimation is shown to improve video coding efficiency of both H.264 and HEVC standards. In this paper we introduce enhanced skip and direct modes for H.264 coding using decoder-side ...

Wavelet image coding using the spherical representation 

Ateş, Hasan Fehmi; Orchard, Michael T. (IEEE, 2005)
In this paper, we introduce the "spherical representation", which provides a new adaptive framework for modeling and coding the image information in wavelet subbands. Based on this representation, a practical coding algorithm ...

Fast inter-mode decision and selective quarter-pel refinement in H.264 video coding 

Ateş, Hasan Fehmi (IEEE, 2008)
In H.264 video coding standard, there exist several inter - prediction modes that use macroblock partitions with variable block sizes. Choosing a rate-distortion optimal coding mode for each macroblock is essential for the ...
