Digital image technique    Digital Image Technique   Introduction :-   A digital image is an array of no depicting spatial distribution of a certain field or parameter.   It is digital representation in the form of row and columns , where each number of array represents the relative value of the parameter at that point/over the unit area.       Source of multispectral image data   The various types of scanner used on areal and space borns platforms constitute the basic source and provide the bulk of remote sensing multispectral digital imagery.     Techniques of digital image processing :-      Radiometric correction   Geometric image correction  Image register   Image enhancement   Image filtering   Image transformation   Color of enhancement   Image segmentation   Image fusion   2.5 dimensional visualization   Classification      Click here to get pdf
