Error resiliency transcoding and decoding solutions using distributed video coding techniques
(Elsevier, 2008)This paper proposes a number of video transcoding techniques for the purpose of adding error resiliency. The proposed solutions make use of distributed video coding technologies which were originally reported in the ... -
Feature modeling using polynomial classifiers and stepwise regression
(Elsevier, 2010)In polynomial networks, feature vectors are mapped to a higher dimensional space through a polynomial function. The expanded vectors are then passed to a single layer network to compute the model parameters. However, as ... -
Continuous Arabic Sign Language Recognition in User Dependent Mode
(Scientific Research, 2010)Arabic Sign Language recognition is an emerging field of research. Previous attempts at automatic visionbased recognition of Arabic Sign Language mainly focused on finger spelling and recognizing isolated gestures. In this ... -
Robust Polynomial Classifier Using L1-norm minimization
(Springer, 2010)In this paper we present a robust polynomial classifier based on L1-norm minimization. We do so by reformulating the classifier training process as a linear programming problem. Due to the inherent insensitivity of the ... -
User-independent recognition of Arabic sign language for facilitating communication with the deaf community
(Elsevier, 2011)This paper presents a solution for user-independent recognition of isolated Arabic Sign language gestures. The video based gestures are preprocessed to segment out the hands of the signer based on color segmentation of the ... -
Matrix Encoding for Data Hiding Using Multilayer Video Coding and Transcoding Solutions
(Elsevier, 2012)This paper proposes a multitier data hiding solution in MPEG video using matrix encoding. In the first tier of the proposed solution, raw video is encoded into two layers using multilayer Signal to Noise Ratio (SNR) encoding. ... -
Data Hiding in MPEG Video Files Using Multivariate Regression and Flexible Macroblock Ordering
(IEEE, 2012)This paper proposes two data hiding approaches using compressed MPEG video. The first approach hides message bits by modulating the quantization scale of a constant bitrate video. A payload of one message bit per macroblock ... -
MPEG-2 to HEVC Video Transcoding With Content-Based Modeling
(IEEE, 2013)This paper proposes an efficient MPEG-2 to HEVC video transcoder. The objective of the transcoder is to migrate the abundant MPEG-2 video content to the emerging HEVC video coding standard. The transcoder introduces a ... -
Detection of frame deletion for digital video forensics
(Elsevier, 2013-12)The abundance of digital video forms a potential piece of evidence in courtrooms. Augmenting subjective assessment of digital video evidence by an automated objective assessment helps increase the accuracy of deciding ... -
H.264/AVC to HEVC Video Transcoder Based on Dynamic Thresholding and Content Modeling
(IEEE, 2014)The new video coding standard, HEVC, was developed to succeed the current standard, H.264/AVC, as the state of the art in video compression. However, there is a lot of legacy content encoded with H.264/AVC. This paper ... -
Evaluation of the contribution of flexural CFRP plates in shear strengthening RC beams
(Conference on Smart Monitoring, Assessment and Rehabilitation of Civil Structures, 2015)Strengthening of RC beams for shear has been typically done by externally attaching strips of steel plates or carbon-fiber reinforced polymer (CFRP) sheets or plates on the sides of the beams. However, sides of beams ... -
H.264/AVC Motion Vector Concealment Solutions Using Online and Offline Polynomial Regression
(Springer, 2015)This paper introduces two polynomial regression solutions for error concealment by predicting the values of motion vectors of lost macroblocks. The two solutions are online and offline polynomial regression modeling. In ... -
Saturation Loadings on 13X (Faujasite) Zeolite above and below the Critical Conditions, Part I: Alkane Data Evaluation and Modeling
(Springer, 2015)The saturation loadings for subcritical adsorption of n-, iso- and neo alkanes C1 –C8 in 13X zeolite are modeled using the modified Rackett model of Spencer and Danner (1972) for the saturated liquid densities combined ... -
Glove-Based Continuous Arabic Sign Language Recognition in User-Dependent Mode
(IEEE, 2015)In this paper we propose a glove-based Arabic sign language recognition system using a novel technique for sequential data classification. We compile a sensor-based dataset of 40 sentences using an 80-word lexicon. In the ... -
A regression-based framework for estimating the objective quality of HEVC coding units and video frames
(Elsevier, 2015-05)A no-reference objective quality estimation framework is proposed. The framework is suitable for any block-based video codec. In the proposed solution, features are extracted from coding units and summarized to form features ... -
External strengthening of shear deficient reinforced concrete beams with flexural CFRP laminates
(International Workshop on Performance, Protection & Strengthening of Structures under Extreme Loading (PROTECT 2015), 2015-06)This paper presents an experimental investigation of reinforced concrete (RC) beams strengthened in shear with externally bonded flexural carbon-fiber reinforced polymer (CFRP) sheets attached to the soffit of the beam via ... -
Hydrogen Supplement Co-combustion with Diesel in 2 Compression Ignition Engine
(Elsevier, 2015-10)The present work investigates experimentally the behavior of compression ignition engine while boosting the combustion by enriching air-intake manifold with hydrogen supplement at the atmospheric condition. The study reports ... -
Strengthening of thin reinforced concrete slabs with CFRP laminates
(International Conference on Advanced Composite Materials in Bridges and Structures, 2016)Over the years, engineers and researchers have been working continuously to reduce the dead loads on buildings by reducing the sizes of structural elements. Slabs add significant dead load to buildings compared to other ... -
Modeling the fire response of concrete beams reinforced with GFRP beams
(International Conference on Advanced Composite Materials in Bridges and Structures, 2016)In the last two decades, researchers and engineers studied the possibility of reinforcing slabs and beams with fiber-reinforced polymer (FRP) bars instead of the conventionally used steel reinforcement. Such FRP bars have ... -
A Unified Approach for Probability of Detection Evaluation over Generalised Fading Channels
(Institution of Engineering and Technology, 2016)In this paper, we revisit energy detection-based spectrum sensing cognitive radio systems operating over generalised fading channels. In particular, we derive closed-form exact expressions as well as lowand high-signal-to-noise ...
