A few questions about doing a Gaussian Fit :

1) Is gaussian fit and gaussian regression the same thing ?
2) I have a gaussian function that will return a list of gaussian numbers giving an initial list length. So if you input 5 you will get:
1,2,6,4,1.
My question is if I have an image and I want to do a gaussian fit on the Rows and the Columns and graph them separately.
would I :
A) Add up all values in rows 1- 5, than multiply the value from row 1 to 1, multiply the value from row 2 to 2 , row 3 to 6, row 4 to 1, and row 5 to 1 and then repeat for the columns?
or
B) Add up all the values in my rows, then solve for the mean value, and then I am not sure what would come next ...

or is there something else I should do?

Can you define exactly what a Gaussian fit is?

Can you define exactly what a Gaussian fit is?

When you take data from an image and you fit it into a Bell curve.
Actually when you take any given data.
I am told you do this, because if your data can fit in a bell curve, then you can do other, statistical Analysis to it.

Oh cool!
but could someone answer my questions ?
