Improved Exemplar based Image Inpainting for Partial Instance Occlusion Handling with K-means Clustering and YCbCr Color Space

Deepa Abin, Sudeep D.Thepade
2021 International Journal of Advanced Computer Science and Applications  
The exemplar inpainting method is improved through the color quantization with K-means clustering approach in YCbCr color space.  ...  There is a need for a restoration method that finds improved subjective perception and execution time. The proposed work focuses on novel amended exemplar model to improve the subjective perception.  ...  Here Kmax was fixed to 50 empirically as it was quite enough from a subjective point of view where more number of colors may pose difficulties in color identification itself.  ...

Exemplar-Based Image Inpainting Using a Modified Priority Definition

Liang-Jian Deng, Ting-Zhu Huang, Xi-Le Zhao, Jesus Malo
2015 PLoS ONE  
Traditional exemplar-based algorithms are to search suitable patches from source regions to fill in the missing parts, but they have to face a problem: improper selection of exemplars.  ...  Exemplar-based algorithms are a popular technique for image inpainting. They mainly have two important phases: deciding the filling-in order and selecting good exemplars.  ...  The first author is also supported by Outstanding Doctoral Students Academic Support Program of UESTC [23] ; (d) The method "07'TPAMI" by Wexler et al.  ...
