Suppose I would like to read a mystery book, and my only condition for selection is that it is good.
I walk to the mystery section, but there are too many choices.
Wouldn't it be nice if I could just take a picture of the shelf to instantly search for all the book reviews online?
Given an image of a bookshelf, Bookshelf Scanner segments the spines of books, isolates the text elements on the spines, and performs OCR on the result.
Then it Googles the results to find the most promising link to a book review web site.
