• Is required for this assuming a scanner with 300 x 600 resolution is used and S bits are used per pixel?
• Solution. Storage needed for I photo = 300 x 600 x 3.5 x 5.5 x 8 bits = 3.465 MB
• Storage for 1000 old photos = 3465 MB - 3.465 GB
• which requires many CDs to store!
• From the above example, we sec that considerable amount of storage is needed to store pictures. If a large photo archive is to be preserved, it is essential to reduce the storage needed without sacrificing quality. This is possible and is done by what are known as compression algorithms which remove redundant pixels without sacrificing quality. From the compressed picture the original picture is reconstructed by another algorithm without losing fidelity. We will describe the idea used by such algorithms later in this chapter.
