Abstract

Rectification may be considered as the transformation process of digital images carried out to obtain distortion free versions of the images. Transformation parameters are obtained by using ground control points (GCP) on the uncorrected raw image and their corresponding points on the map or on an ortho-rectified image. At the end of the geometric transformation, to obtain the pixel values of the new image a radiometric resampling is required. For this purpose, interpolation techniques are used. In this paper, in order to perform rectification issues, we used Restore 1.0 software which we developed for rectification of digital images, in Borland C++ Builder platform.
