Certkiller had designed a new system for processing and then viewing the studentrecords from the Web.
Each student has one image(8½” x 11″) that was scanned at 300 dpi and when compressed takes up
approximate 52KB of space.
Which of the following methods has been used to store the image?

A.
DjVu

B.
LDF LuraDoc

C.
ITU (CCITT) Group IV

D.
ITU (CCITT) Group III

Explanation:
Group 3 is 10% compression.
Group 4 is 20% compression.
This is the right size for Group 4 image – 50k for 300 dpi, and 20k for 200 dpi.
