The changes of the image into a numeric code which will be comprehend by a computer system is digitization. This can be achieve by a connection between a frame grabber boarding in the computer . The initial stage of digital image processing is the transformation of an image into a computer system. Transforming it into an image which can be stored in the computer's memory or CD-ROM or on a hard disk
