Hi,
I have a tiff image of the dimesion 3000 x 3000 which is actually a
gray scale image.I want to calculate the amount of soil,water and air
present in the image.I tried using histogram to apply threshold but
its not working fine.Can anyone suggest me how to do it.I am an
invoice so any help would be appreciated.Below is the code which i
have used.

nPixels = n_elements(rotateImg)

soilSubscripts = where(rotateImg ge 24000and rotateImg lt 30000,
nSoilPixels)

percentSoil = float(nSoilPixels) / nPixels

waterSubscripts = where(rotateImg ge 18000 and rotateImg lt 23000,
nWaterPixels)

percentWater = float(nWaterPixels) / nPixels

PRINT, percentSoil
PRINT, percentWater

With Regards
Arun
