- Abstract
- Image inpainting is the art of modyng part of image or video that cannot
detectable by ordinary observer. There are two dierent classes of algorithms
for inpainting. Texture synthesis, and geometric partial dierential
equations(PDEs). We think that we don't have to make new color in image
so we only focus on nd the best matching pixels for each unknown pixels.
In this paper, we suggest a new method based on exemplar based inpainting.
The method is suggested by Criminisi et al. [1]. But its method takes a long
time, but also cannot give a good result for some cases. First, we analyze
deciency of Criminisi algorithm and then we oer a new algorithm. Our
algorithm uses a modied calculation for priority and then uses patch ratio
for nding the best candidates. For faster computing, we use window and
number of nonzero elements of candidates. Finally, among the candidates we
concern about gradients of the template.
