Image inpainting apparatus and method using restricted search region
First Claim
1. An image inpainting apparatus using a restricted search region, the apparatus comprising:
- a target region setup unit for setting a target image region to be inpainted in response to an image inpainting request;
a surrounding region setup unit for setting a surrounding image region which has a preset size and comprises the set target image region;
a similar region division unit for setting a plurality of similar image regions by grouping similar pixels in the set surrounding image region, and dividing the surrounding image region into the plurality of set similar image regions;
a search region setup unit for dividing the target image region according to the similar image regions, and setting a search region of each divided target image region; and
an inpainting processing unit for detecting an image of an image region most similar to each divided target image region from the set search region of each divided target image region, and copying and pasting the detected image into each corresponding target image region.

Abstract
Disclosed is an image inpainting apparatus and method using a restricted search region. The image inpainting apparatus sets a target image region to be inpainted in response to an image inpainting request, sets a surrounding image region, which has a preset size and includes the set target image region, sets a plurality of similar image regions by grouping similar pixels in the surrounding image region, divides the surrounding image region into the plurality of set similar image regions, divides the target image region according to the similar image regions, sets a search region of each divided target image region, and detects an image of an image region most similar to each divided target image region from the set search region of each divided target image region, thereby performing image inpainting. Accordingly, image inpainting is performed using a search region, which has been determined to include a similar image most similar to an image to inpaint, so that it is possible to increase the probability of searching for an image most similar to the inpainting image region.
