introduction: wavelet transform is one of the useful and suitable tools for time series and signal analysis. nowadays wavelet transform is frequently used in geophysical data processing and interpretation, especially seismic data. however, the use of this method isn’t widespread in gravity and geomagnetic. fedi and quarta (1998), martelet et al. (2001) and de oliveira lyrio (2004) used the wave...

This paper proposes a gray-scale inverse Hough transform (GIHT) algorithm which is combined with a modified gray-scale Hough transform (GHT). Given only the data of the Hough transform (HT) space and the dimensions of the image, the GIHT algorithm reconstructs correctly the original gray-scale image. As a first application, the GIHT is used for line detection and filtering according to conditio...

Due to significant geometric distortions and illumination differences, developing techniques for high precision robust multisource remote sensing image registration poses a great challenge. This article presents an iterative approach, called scale-invariant feature transform (ISIFT) images, which extends the traditional (SIFT)-based system close-feedback SIFT that includes rectification feedbac...
