Finding the rms value for the entire object [India] 

+++

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.
