This enhancement technique was carried out in order to produce better an image
classification for digital classification. The images surrounding area appear much better after performed enhancement technique. Brightness and contrast level panels were used to adjust the image view to an appropriate level. The image after enhancement clearly showed the separation of the land cover features. The view of the image after enhancement is better than before enhancement.
We can classify and optical image by using unsupervised classification algorithms
(ISODATA) and then reclassify the output as per our requirement. Only the classes of our
interest can be made visible by setting their opacity to one and others to zero.
