Fit custom model for NIQE image quality score
The custom dataset specified in the image datastore imds
should consist of images that are perceptually pristine to human subjects.
However, the definition of pristine depends on the
application. For example, a pristine set of microscopy images has a different
set of quality criteria than images of buildings or outdoor scenes. When
training a custom NIQE model, use images with varied image content and with
potentially different sets of quality criteria.
