Finding the rms value for the entire
object
+++
I am doing the project n measurement of surface roughness using
image processing. Can anybody give me idea of how to measure the rms
value by image processing techinque. If anybody knows please send me
reply to me, it will be very helpful to me.

To my knowledge there is no over all imaging rms system for the
whole part. What is normal is to take readings randomly on a part and
to use the average of at least 3 to 5 readings, but part size is also
a factor. More readings maybe required.
