For feature selection in image processing, there are some references in the following paper:
Qiu, P., and Xing, C. (2013), "Feature Based Image Registration Using
Non-Degenerate Pixels," Signal Processing, 93, 706--720.
For profile monitoring and other statistical process control methods, see my
recent book:
Qiu, P. (2014), Introduction to Statistical Process Control, Boca Raton, FL:
Chapman & Hall/CRC.
Hope these informations are helpful.
