INFORMATION PROCESSING DEVICE, IMAGE MODIFICATION METHOD, AND COMPUTER PROGRAM PRODUCT

摘要

According to an embodiment, an information processing device includes: a first division unit divides an image into a text containing region and a background region other than the text containing region; a second division unit divides a text containing region into a character region constituted by lines forming characters and a character background region other than the character region; a calculator calculates a first representative value of an attribute of the character region, a second representative value of the attribute of the character background region, and a third representative value of the attribute of the background region; a modification unit makes modification so that a first difference based on the first and third representative values, a second difference based on the first and second representative values, and a third difference based on the second and third representative values become larger; and an output unit outputs a modified image.

主权项

1. An information processing device comprising:
an acquisition unit to acquire an image; a first division unit to divide the image into a text containing region containing one or more characters and a background region other than the text containing region; a second division unit to divide the text containing region into a character region constituted by lines forming the characters and a character background region other than the character region; a calculator to calculate a first representative value of a predetermined attribute of the character region, a second representative value of the predetermined attribute of the character background region, and a third representative value of the predetermined attribute of the background region; a modification unit to modify at least one of the first representative value, the second representative value, and the third representative value in such a way that a first difference based on the first representative value and the third representative value, a second difference based on the first representative value and the second representative value, and a third difference based on the second representative value and the third representative value become larger; and an output unit to output a modified image obtained by
changing the value of the predetermined attribute of the character region to a modified first representative value when the first representative value is modified,changing the value of the predetermined attribute of the character background region to a modified second representative value when the second representative value is modified, orchanging the value of the predetermined attribute of the background region to a modified third representative value when the third representative value is modified.
