many factors such as γ. One can not make the general conclusion that tNM is always better
than TOD and TCD. The plots in Figure 9.9 for example, show the results of comparison
of image 8 with the rest of images, where all three measures are consistent with each other.

Conclusion
A new similarity measure for perceptual comparison and analysis of images has been in-
troduced in this chapter.
The proposed similarity measure called tolerance cardinality
