Discussion
In the process of digitization, "Digitization step" includes ........
(i) Image capturing
(ii) Selection of documents
(iii) OCR
(iv) Image cleaning
Answer: D
The digitization step includes i, iii and iv, so the answer is (i), (iii) and (iv) are correct.
The digitization step itself covers capturing the images by scanning or photography (i), cleaning the images to remove noise, skew and marks (iv), and running optical character recognition to produce searchable text (iii).
Selection of documents (ii) is done earlier, at the planning stage, when the library decides which materials to digitize on grounds such as value, demand, condition and copyright. Options including ii are therefore wrong.
