Hello,

Greetings o f the day!

I want to find the mean intensity of the domain for various positions For

convenience, I have attached two images. What I mean by domain is shown by

green circle on each image. It is to be noted that the domains are changing

its orientation at various positions. And here the problem starts.

1. If I do the oval or circular selection and then crop the image and find

the mean intensity for various positions, it's not perfectly covering the

area of the domain.

2. If I do free hand selection and try to cover the domain for each

position, then, the area of the selection is different for each case, and

thus make the mean intensity variation. If this is the case, the variation

of intensity is coming because of the difference in the area, not from the

domain which is not correct.

What should I do? It will be very helpful, if I get some suggestions.

Thanks

Anu
