The Added Value of Stratified Topographic Correction of Multispectral Images
Satellite images in mountainous areas are strongly affected by topography. Different studies demonstrated that the results of semi-empirical topographic correction algorithms improved when a stratification of land covers was carried out first. However, differences in the stratification strategies proposed and also in the evaluation of the results obtained make it unclear how to implement them. ...
متن کاملEvaluation and Comparison of Topographic Correction Models Is Applied on the Series Landsat Images Using Spectrometery Data
The effect of topography on the radiance record in satellite image, probably reduce the accuracy of algorithem impliementation on the images . Therefore, to reduce the effect of topography, various correction models based on interaction between light and object needs to be defined. This research introduces lombertin correction model (Cosine model) and non_lombertin correction model (mineart and...
متن کاملTwo New Methods of Boundary Correction for Classifying Textural Images
With the growth of technology, supervising systems are increasingly replacing humans in military, transportation, medical, spatial, and other industries. Among these systems are machine vision systems which are based on image processing and analysis. One of the important tasks of image processing is classification of images into desirable categories for the identification of objects or their sp...
متن کاملComparison of Topographic Correction Methods
A comparison of topographic correction methods is conducted for Landsat-5 TM, Landsat-7 ETM+, and SPOT-5 imagery from different geographic areas and seasons. Three successful and known methods are compared: the semi-empirical C correction, the Gamma correction depending on the incidence and exitance angles, and a modified Minnaert approach. In the majority of cases the modified Minnaert approac...
متن کاملTopographic Maps of Color Images
We address the problem of extending topographic maps to color images. A topographic map gives a morphological and a geometrical representation of the information contained in natural images. Two approaches are presented and discussed. The first one is new and consists in defining a total order in IR3 in accordance with the human visual perception of shapes. This allows to define color topograph...
