The most difficult task in the segmentation of the image is to obtain the segmentation by avoiding almost all the noises within less span of time. The AMG is used for increasing the time step and SFM will be used in decreasing the computation domain. In this technique the number of iterations will be less when compared to the existing systems. The integration of medical images with multimodal M...

Updating cadastral information is crucial for recording land ownership and property division changes in a timely fashioned manner. In most cases, the existing cadastral maps do not provide up-to-date information on land parcel boundaries. Such a situation demands that all the cadastral data and parcel boundaries information in these maps to be updated in a timely fashion. The existing technique...

This paper describes a highly automatic work flow for urban model generation from digital aerial imagery. The images used in our approach feature one high resolution panchromatic channel and four lower resolution channels (red, green, blue and near infrared). In the first step an initial land use classification is performed where a support vector machine is applied to each image. Subsequently t...

Fusion or merging or pansharpening is the digital processing that combines the high spatial and multispectral information to obtain a fused multispectral image that retains the spatial information from the high resolution panchromatic image, as well as the spectral characteristics of the lower resolution multispectral image. Many fusion algorithms were developed and tested on different commerci...

Á trous wavelet transform (AWT) and empirical mode decomposition (EMD) are two distinct methods used for analyzing nonlinear and nonstationary signals. In this paper, a combination of AWT and EMD is proposed as an improvedmethod for fusing remote sensing images on the basis of the framework of AWT-based image fusion. The principle consists of performing a multiresolution decomposition on high r...

Considering of the human visual system and the characteristics of remote sensing images, a novel image fusion strategy is presented for panchromatic high resolution image and multispectral image in nonsubsampled contourlet (NSCT) domain. The NSCT can give the asymptotic optimal representation of the edges and contours in image by virtue of the characteristics of good multiresolution, shift-inva...

The pistachio (Pistacia.vera) belongs to the Anacardiaceae family. Plants of this family are trees or shrubs (broadleaf) and in total comprising 75 genera and 600 species. This species is found in arid and semi-arid regions, located in the northeast of Iran. Many algorithms have been investigated for tree delineation and identification, in order to assist human operators in the information expl...

Image data sharpening is a challenging field of remote sensing science, which has become more relevant as high spatial-resolution satellites and superspectral sensors have emerged. Although the spectral property is crucial for mineral mapping, spatial resolution is also important as it allows targeted minerals/rocks to be identified/interpreted in a spatial context. Therefore, improving the spa...

Pléiades 1A and 1B are twin optical satellites of Optical and Radar Federated Earth Observation (ORFEO) program jointly running by France and Italy. They are the first satellites of Europe with sub-meter resolution. Airbus DS (formerly Astrium Geo) runs a MyGIC (formerly Pléiades Users Group) program to validate Pléiades images worldwide for various application purposes. The authors conduct thr...

n In 1998, the imaging properties of the Advanced Land Imager on the Earth Observing 1 (EO-1) satellite were calibrated at Lincoln Laboratory under simulated flight conditions. The spatial calibrations estimated the system transfer functions for the various spectral bands, and the line of sight of each detector, relative to a reference cube on the instrument. The Advanced Land Imager is a push-...
