The experiment uses 18 image-quality measures (IQM). These IQM are computed for each frame of the input video, and the feature-sets are used to construct a 2-class classifier via Linear Discriminant Analysis (LDA).

The image-quality measures used here form a subset of the measures proposed by Galbally et al:
