Fast and efficient land-cover classification of multispectral remote sensing data using artificial neural network techniques

Preliminary Site Investigation based on RGB Electromagnetic Energy of Landsat-7 Images in Wadi Fayidah, Saudi Arabia

“…Lineaments usually reflect linear structural features in the rocks or artificial features like roads or buildings. Lineament extraction is usually carried out by using digital data of satellite either manually [23][24] or automatically [25][26]. The automatic lineament extraction technique is applied in this work to interpret and extract the structural lineaments from the digital SPOT-5 data of the study area.…”

Three-Dimensional Lineament Visualization Using Fuzzy B-Spline Algorithm from Multispectral Satellite Data

“…Majumdar and Bhattacharya (1998) reported that Haar transform is proper in extraction of subtle features with finer details from satellite data. Vassilas et al (2002), however, reported that Hough transform is appropriate for fault feature mapping. Consequently, Laplacian, Sobel, and Canny are the major algorithms for lineament feature detections in remotely sensed data (Mostafa and Bishta 2005;Semere and Ghebreab, 2006;Marghany 2005).Recently Marghany and Mazlan (2010) proposed a new approach for automatic detection of lineament features from RADARSAT-1 SAR data.…”

“…Image processing tools have used for lineament feature detections are: (i) image enhancement techniques (Mah et al 1995;Chang et al 1998;Walsh 2000;Marghany et al, 2009b); and (ii) edge detection and segmentation (Wang et al 1990;Vassilas et al 2002;Mostafa and Bishta 2005). In practice, researchers have preferred to use the spatial domain filtering techniques in order to get ride of the artificial lineaments and to verify disjoint lineament pixels in satellite data (Süzen and Toprak 1998).…”

“…Almost anything that showed as a roughly straight line in an image was suspected to be geological. Most of these lineaments were attributed either to faults or to fracture systems that were controlled by joints (fractures without relative offsets) (Wang et al 1990;Vassilas et al 2002;Robinson et al, 2007).…”

“…In fact, the High Pass filter selectively enhances the small scale features of an image (high frequency spatial components) while maintaining the larger-scale features (low frequency components) that constitute most of the information in the image. Majumdar and Bhattacharya (1998) and Vassilas et al (2002), respectively have used Haar and Hough transforms as edge detection algorithms for lineament detection in Landsat-TM satellite data. Majumdar and Bhattacharya (1998) reported that Haar transform is proper in extraction of subtle features with finer details from satellite data.…”
