DIGITAL IMAGE PROCESSINGM inakshi KumarPhotogrammetry and Remote Sensing DivisionIndian Institute of Remote Sensing, Dehra DunAbstract : This paper describes the basic technological aspects of DIGITAL ImageProcessing with special reference to satellite IMAGE PROCESSING . Basically, all satelliteimage- PROCESSING operations can be grouped into three categories: ImageRectification and Restoration, Enhancement and Information Extraction. The formerdeals with initial PROCESSING of raw IMAGE data to correct for geometric distortion,to calibrate the data radiometrically and to eliminate noise present in the enhancement procedures are applied to IMAGE data in order to effectively displaythe data for subsequent visual interpretation.
86 Digital Image Processing have been found to be most satisfactory than the photographic technique for image enhancement, because of the precision and wide variety of digital processes. Contrast Contrast generally refers to the difference in luminance or grey level values in an image and is an important characteristic. It can be defined as the ...
