abstract

The study of subjective visual quality, and the development of computed quality metrics, require accurate and meaningful measurement of visual impairment. A natural unit for impairment is the JND. In many cases, what is required is a measure of an impairment scale, that is, the growth of the subjective impairment, in JNDS, as some physical parameters is increased.
