6. Image Processing
 Digital image processing is a technology of applying a number of computer
algorithms to process a digital image.
 Back in 1980’s, after computer gain enough speed and memory.
 It includes:
 Image acquisition
 Image processing
 The result can either:
 An image.
 Or a set of representative characteristic of original image.
 Like: Classified images

a) Original RGB Image
b) R-component
c) G-component
d) B-component

8. Why Image Processing?
Its Human erg to get from Better to Best 
 To have a high Quality images.
 To see beyond the human visionary.
 To have a precise interpretation.
 To extract the hidden information.
 To utilize the maximum of the available.
 To get a better idea before getting into real-time work-out, like surveying.

9. Where to use Image Processing?
 Remote sensing (e.g. satellite imagery)
 Geographic Information System (e.g. image processing)
 Medical imaging (e.g. X-ray, CT Scan, MRI)
 Forensics (e.g. finger-prints)
 Military (e.g. detection, tracking)
