Rate-distortion and complexity joint optimization for fast motion estimation in H.264 video coding
(IEEE, 2006)
H.264 video coding standard offers several coding modes including inter-prediction modes that use macroblock partitions with variable block sizes. Choosing a rate-distortion optimal mode among these possibilities contributes ...
Fast inter-mode decision and selective quarter-pel refinement in H.264 video coding
(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 ...
Wavelet image coding using the spherical representation
(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 ...
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 ...
Disaster damage assessment for buildings using self-similarity descriptor
(Institute of Electrical and Electronics Engineers Inc, 2015)
Assessment of damage caused by an earthquake is significant for coordinating emergency response teams and planning emergency aid. In this study, a robust method is proposed for detecting damaged buildings using pre- and ...
Decoder-side super-resolution and frame interpolation for improved H.264 video coding
(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 ...
A bit-serial sum of absolute difference accelerator for variable block size motion estimation of H.264
(IEEE, 2009)
Bit-serial architectures offer a number of attractive features over their bit-parallel counterparts such as smaller area cost, lower density interconnection, a reduced number of pins, higher clock frequency, simpler routing ...
Kernel likelihood estimation for superpixel image parsing
(Springer Verlag, 2016)
In superpixel-based image parsing, the image is first segmented into visually consistent small regions, i.e. superpixels; then superpixels are parsed into different categories. SuperParsing algorithm provides an elegant ...
Battle damage assessment based on self-similarity and contextual modeling of buildings in dense urban areas
(IEEE, 2016)
Assessment of battle damages is significant both for tactical planning and for after-war relief efforts. In this study damaged buildings are detected using self-similarity descriptor in pre- and post-war satellite images. ...
