Discussion for Lab 4, ECE637, Spring 2013
Additional Information
Before you jump into the lab, there is actually a difference for the monitors everyone is using. To ensure consistent result throughout the lab, I would suggest using the same monitor while doing calibrations!
Basic knowledge for gamma correction

Extended information for something to do when you are bored
Fun experiment to do on your monitor(s)
Q&A Section
- Q: My image looks really dark after correction.
- A - Make sure you have both nullification and correction set correctly.
- Q: In problem 3, I checked the "stretch" function in matlab help, but I did not find it. I got "stretchlim" from matlab help. Why do we need to use the syntax "stretch"?
- A - I believe the lab is written that way so that you could write the equalization into function calls
