Mohsen Esmail nezhad soltanloo; Mahmod Reze Sahebi

Volume 10, Issue 4 , February 2019, , Pages 121-144

  Polarimetric Interferometric SAR (POLINSAR) data by providing wealth of information containing intensity, polarimetric and interferometric measurements, have shown many capability of mentioned data in the land cover classification. These three componentes of POLINSAR data could be found independently ...  Read More

Improvement of Markov Random Field Technique for Unsupervised Change Detection from Multichannel SAR Images

S Salehi; M.J Valadan Zoej; M. Sahebi

Volume 9, Issue 2 , December 2017, , Pages 21-40

  In applications related to environmental monitoring and disaster management, multichannel synthetic aperture radar (SAR) data present a great potential, owing both to their insensitivity to atmospheric and Sun-illumination conditions and to the improved discrimination capability they may provide as compared ...  Read More

Measurement of Surface Changes and Velocity fields of Alam-chal Glacier Using Satellite Imagery and Aerialphotos

, Y Rezaei; , M.J. Valadan Zouj; , M.R Sahebi

Volume 9, Issue 1 , October 2017, , Pages 1-16

  Mountain Glaciers are pertinent indicators of climate change and their surface velocity changes, are an essential climate variable. In order to retrieve the climatic signature from surface velocity, large scale study of glacier changes is required. Satellite remote sensing is an effective way to derive ...  Read More

Evaluating and Improving the Functionality of Simulated Annealing Algorithm for Sub-pixel Land Cover Mapping Using Multispectral Imagery

Jadidi Milad Niroumand; Mehdi Mokhtarzade; Mahmood Reza Sahebi

Volume 7, Issue 3 , November 2015, , Pages 1-16

  The mixed pixels are considered as a major challenge in land cover mapping procedure from satellite imagery. Developments of the spectral unmixing and soft classification methods have provided the possibility for estimation of class proportions within the pixels. However, sub-pixel land cover mapping ...  Read More
