Image Quality Evaluation in Lossy Compressed Images
… research focuses on the quantification of image quality in lossy compressed images, exploring the impact of digital artefacts and scene characteristics upon image quality evaluation. A subjective paired comparison test was implemented to assess perceived quality of JPEG 2000 against baseline JPEG …

Digital Watermarking Based Image and Video Quality Evaluation
Image and video quality evaluation is very important. In applications involving signal transmission, the Reduced- or No-Reference quality metrics are generally more practical than the Full-Reference metrics. Digital watermarking based quality evaluation emerges as a potential Reduced- or …

Computer vision based corn kernel quality evaluation: Traditional versus machine learning
Corn kernel quality evaluation is a trivial task for experienced farmers and agriculture researchers, but it becomes tricky if we try to develop a computer vision based automatic solution. In this thesis, we present two approaches for this problem, briefly introduce the data sets corresponding to …

A Modified Bayesian Power Prior Approach with Applications in Water Quality Evaluation
… frequently encountered in environmental water quality evaluation. Many times, the sample size of water monitoring data is too small to have adequate power. Here, we present a Bayesian power prior approach by incorporating the current data and historical data and/or the data collected at …

A subsurface water quality evaluation system for assessing NPS pollution potential by pesticides
A watershed scale water quality evaluation system was developed for assessing spatial variation of subsurface pesticide movement. The system consists of a linked-transport model component for performing simulation and a GIS component for processing spatially-related data. The surface heterogeneity …
