Optimal presentation duration for video quality assessment

Does the length of a video sequence affect the reliability of a viewer’s quality assessment? With the aim of increasing data collection efficiency and reducing processing times, this project aims to identify how long video sequences should be in subjective video quality assessment studies.

Undecimated 2D Dual Tree Complex Wavelet Transforms

This work introduces two undecimated forms of the 2D Dual Tree Complex Wavelet Transform (DT-CWT) which combine the benefits of the Undecimated Discrete Wavelet Transform (exact translational invariance, a one-to-one relationship between all co-located coefficients at all scales) and the DT-CWT (improved directional selectivity and complex subbands).

Home Activity Monitoring Study using Visual and Inertial Sensors

The objective of this project is to present a comparative study towards activity monitoring using these visual and accelerometer sensors in daily living scenarios.
