Video Quality Software

No-Reference (NR) Metric Framework

Click here to go to the no-reference (NR) Metric Framework GitHub repository.

The NRMetricFramework repository provides the information, support tools, and datasets required to begin research on NR metrics for image quality assessment (IQA) or video quality assessment (VQA). The GitHub wiki pages provide help, tutorials, and links to related resources.   

Video Quality Metric (VQM) Software

Click here to go to the VQM GitHub repository. See readme.md and cvqm.md for information on the VQM tools.

Web-Enabled Subjective Test (WEST)

The Web-Enabled Subjective Test (WEST) software package offers a solution to the problem of gathering subjective testing data from multiple locations and multiple portable or computing devices. The software is freely available for download.

This software was released in 2012 and will need to be updated due to changes that have occurred in operating systems.

Spatial Information (SI) Filter

MATLAB® code implementing the spatial information (SI) filter is available in the NRMetricFramework GitHub repository, file filter_si_hv_adapt.m. This filter detects long edges and estimates edge angle. 

Subject Screening

MATLAB® code implementing subject screening techniques.

Iterated Nested Least Squares Algorithm (INLSA)

MATLAB® code implementing INLSA. This algorithm that allows multiple subjective datasets to be fitted to a single subjective scale. INLSA computes the fit from a common set of objective metrics.
