Automatic Segmentation of a region [message #29633]

Hi,
I have a small problem in segmentation. I first threshold a image and
then i perform morphological operations on the binary image. Using
label_regions i've identified all the blobs. I used the where function
to get the regions in each blob. I have one huge blob and the rest are
small. I want to make all the pixels in the small blob as 0.
I tried the following:

Method1:

im = Origimage and morphimage
tv,image

Method 2:

for j = 1, noofblobs do begin
region = Where (morphimage eq j)
Area = n_elements(region)
if (Area le 80000) then begin
morphimage[region] = 0B
endif
endfor

Both didn't work and i get a black screen.

Can anybody please help me.

Thank you for ur help in advance.

Cheers,
Akhila.
