Hello Mr.Mark:
Sorry for that annoying mail.
U have got it right. I have read the documentation carefully. Let me
explain it fully. Using region grow, i have obtained a vector of
indices (1-d). Now, suppose image is my image array. i have to compute
the geometric area of the roi whose indices are the returned array.
i also know oroi = obj_new('idlanroi', some array]
let me know what the some array will be in the above scenario. it has
to be a 2-d or 3-d array.
thanks
pravesh
