One of the main problems of optical remote sensing is clouds and cloud shadows caused by specific atmospheric conditions during data acquisition. These features limit the usage of acquired images and increase the difficulty in data analysis, such as normalized difference vegetation index values, misclassification, and atmospheric correction. Accurate detection and reliable cloning of cloud and cloud shadow features in satellite images are very useful processes for optical remote sensing applications. In this study, an automated cloud removal algorithm to generate cloud and cloud shadow free images from multitemporal Landsat-8 images is introduced. Cloud and cloud shadow areas are classified by using process-based rule set developed by using spectral and spatial features after applying simple linear iterative clustering superpixel segmentation algorithm to the image to find cloud pixel groups easily and correctly. Segmentation-based cloud detection method gives better results than pixel-based for detection of cloud and cloud shadow patches. After detection of clouds and cloud shadows, cloud-free images are created by cloning cloudless regions from multitemporal dataset. Spectral and structural consistency are preserved by considering spectral features and seasonal effects while cloning process. Statistical similarity tests are applied to find best cloud-free image to use for cloning process. Cloning results are tested with the structural similarity index metric to evaluate the performance of cloning algorithm.

A new differential geometric method to rectify digital images of the earth's surface using isothermal coordinates Karslıoğlu, Mahmut Onur; Friedrich, E (Institute of Electrical and Electronics Engineers (IEEE), 2005-03-01) A new method to rectify monoscopic digital images and generate orthoimages of the earth's surface is described. It replaces the standard procedure, which transfers the perspective projection of a frame photograph to an orthographic projection of pixels onto a reference plane using corresponding corrections. Instead, the perspective forward projection is kept but every pixel is vertically mapped along the surface normal onto a curved reference surface, for example, the ellipsoid of the World Geodetic System ...
Effects of implementing satellite observed aerosols into a mesoscale atmosphere model Bay, Emine; Yücel, İsmail; Kovacs, Tom; Mccormick, M. Patrick (Informa UK Limited, 2011-01-01) This study investigated the performance of the fifth-generation Pennsylvania State University-National Center for Atmospheric Research (PSU-NCAR) Mesoscale Model (MM5) in calculating the aerosol forcing on cloud cover, incoming surface solar radiation, and near-surface air temperature via the implementation of aerosol optical depth in the shortwave radiation parameterization. MM5 simulations with and without aerosol data are performed in the periods of 6-7 August 2003 and 19-21 September 2003 during which s...
A Novel Two-Way Finite-Element Parabolic Equation Groundwave Propagation Tool: Tests With Canonical Structures and Calibration Apaydin, Gokhan; Ozgun, Ozlem; Kuzuoğlu, Mustafa; Sevgi, Levent (Institute of Electrical and Electronics Engineers (IEEE), 2011-08-01) A novel two-way finite-element parabolic equation (PE) (2W-FEMPE) propagation model which handles both forward and backward scattering effects of the groundwave propagation above the Earth's surface over irregular terrain paths through inhomogeneous atmosphere is introduced. A Matlab-based propagation tool for 2W-FEMPE is developed and tested against mathematical exact and asymptotic solutions as well as the recently introduced two-way split-step PE model through a canonical validation, verification, and ca...
Automatic detection of earthquake-damaged buildings using DEMs created from pre- and post-earthquake stereo aerial photographs Turker, M; Cetinkaya, B (Informa UK Limited, 2005-02-20) This study presents detection of the collapsed buildings caused by, earthquake,, using digital elevation models (DEMs) created from pre- and post -earthquake stereo aerial photographs. It is based on the idea that changes in the height, of collapsed buildings can be detected. The study was conducted using aerial: photographs taken before (1994) and after (1999) the lzmit earthquake in. Turkey. DEMs were created automatically from both pre- and post-earthquake. aerial photographs at 5m spatial resolution. Th...
A Novel Method to Detect Shadows on Multispectral Images Sevim, Hazan Daglayan; Çetin, Yasemin; Baskurt, Didem Ozisik (2016-09-28) Shadowing occurs when the direct light coming from a light source is obstructed by high human made structures, mountains or clouds. Since shadow regions are illuminated only by scattered light, true spectral properties of the objects are not observed in such regions. Therefore, many object classification and change detection problems utilize shadow detection as a preprocessing step. Besides, shadows are useful for obtaining 3D information of the objects such as estimating the height of buildings. With perva...
