, Takes the input digital image and processes it to produce an output image
in the digital binary form
Image Display, Storage, and Communication - ✔✔The output digital image
must be converted into an analog signal before it can be displayed on the
monitor using the DAC
Can be stored on a disk or sent electronically through networks
Image Formations and Representations of Analog Images - ✔✔Analog
images are continous images - X-ray images
Image Formation and Representations of Digital Images - ✔✔Numerical
representations or images of objects
Requires a digital computer
Any info entered into a computer must be converted into digital form
(numbers)
ADC - converts continuous signals to discrete signals
Digital Image Processing - ✔✔Converting an input image into an output
image
Both analog - analog processing
Both digital - digital processing
