WHY DO WE PROCESS IMAGES? WHY DO WE PROCESS IMAGES?

 Acquire an image

 Correct aperture and color balance  Reconstruct image from projections

 Prepare for display or printing

 Adjust image size  Halftoning

 Facilitate picture storage and transmission

 Efficiently store an image in a digital camera  Send an image from Mars to Earth

 Enhance and restore images

R t h f ld i

 Remove scratches from an old movie  Improve visibility of tumor in a radiograph

 Extract information from images

 Read the ZIP code on a letter  Read the ZIP code on a letter  Measure water pollution from aerial images
