A computational visual saliency model for images. (2021)
Thesis
NARAYANASWAMY, M. 2021. A computational visual saliency model for images. Robert Gordon University, MRes thesis. Hosted on OpenAIR [online]. Available from: https://doi.org/10.48526/rgu-wt-1447310

Human eyes receive an enormous amount of information from the visual world. It is highly difficult to simultaneously process this excessive information for the human brain. Hence the human visual system will selectively process the incoming informati... Read More about A computational visual saliency model for images..

A low-complexity wavelet-based visual saliency model to predict fixations. (2020)
Conference Proceeding
NARAYANASWAMY, M., ZHAO, Y., FUNG, W.K. and FOUGH, N. 2020. A low-complexity wavelet-based visual saliency model to predict fixations. In Proceedings of 27th Institute of Electrical and Electronic Engineers (IEEE) International conference on electronics, circuits and systems 2020 (ICECS 2020), 23-25 November 2020, [virtual conference]. Piscataway: IEEE [online], article ID 9294905. Available from: https://doi.org/10.1109/ICECS49266.2020.9294905

A low-complexity wavelet-based visual saliency model to predict the regions of human eye fixations in images using low-level features is proposed. Unlike the existing wavelet-based saliency detection models, the proposed model requires only two chann... Read More about A low-complexity wavelet-based visual saliency model to predict fixations..

A simple encoder scheme for distributed residual video coding. (2020)
Journal Article
HU, C., ZHAO, Y., YU, L., JIANG, Y. and XIONG, Y. 2020. A simple encoder scheme for distributed residual video coding. Multimedia tools and applications [online], 79(27-28), pages 20061-20078. Available from: https://doi.org/10.1007/s11042-020-08811-y

Rate-Distortion (RD) performance of Distributed Video Coding (DVC) is considerably less than that of conventional predictive video coding. In order to reduce the performance gap, many methods and techniques have been proposed to improve the coding ef... Read More about A simple encoder scheme for distributed residual video coding..

Algorithms and methods for video transcoding. (2019)
Thesis
NAGARAGHATTA, A.S. 2019. Algorithms and methods for video transcoding. Robert Gordon University [online], PhD thesis. Available from: https://openair.rgu.ac.uk

Video transcoding is the process of dynamic video adaptation. Dynamic video adaptation can be defined as the process of converting video from one format to another, changing the bit rate, frame rate or resolution of the encoded video, which is mainly...

A computational model of visual attention. (2017)
Thesis
CHILUKAMARI, J. 2017. A computational model of visual attention. Robert Gordon University, PhD thesis.

Visual attention is a process by which the Human Visual System (HVS) selects most important information from a scene. Visual attention models are computational or mathematical models developed to predict this information. The performance of the state... Read More about A computational model of visual attention..

A new video quality metric for compressed video. (2012)
Thesis
BHAT, A.R. 2012. A new video quality metric for compressed video. Robert Gordon University, PhD thesis.

Video compression enables multimedia applications such as mobile video messaging and streaming, video conferencing and more recently online social video interactions to be possible. Since most multimedia applications are meant for the human observer,... Read More about A new video quality metric for compressed video..

Complexity management of H.264/AVC video compression. (2006)
Thesis
KANNANGARA, C.S. 2006. Complexity management of H.264/AVC video compression. Robert Gordon University, PhD thesis.

The H. 264/AVC video coding standard offers significantly improved compression efficiency and flexibility compared to previous standards. However, the high computational complexity of H. 264/AVC is a problem for codecs running on low-power hand held... Read More about Complexity management of H.264/AVC video compression..

Complexity management for video encoders. (2004)
Thesis
ZHAO, Y. 2004. Complexity management for video encoders. Robert Gordon University, PhD thesis.

Software implementation of block-based video coding standards has been used in a wide range of applications. In many cases, such as real-time multimedia systems or power-constrained systems, the coding performance of software-only video encoders and...
