Features Extraction of Landsat 7 Images Using Tasseled Cap Transformation

Abstract

Many of digital processing techniques are used to extract most of the possible information from satellite images, one of these techniques is Tasseled Cap band transformation. This research aims to study the effect of band transformation on the amount and quality of information extracted from Landsat 7 ETM+ images. Multispectral image classification based on raw and Tasseled Cap transformed band were applied. The results showed that the Tasseled Cap give good spectral enhancements and feature extraction which are undistinguishable in raw image, and represent good tool to increase the accuracy of classification.
