摘要
在研究TV修复算法的基础上,提出了一种快速修复算法.利用图像梯度的大小与方向信息对损坏像素直接加权合成,同时按照待修复点邻域内已知像素的梯度方差确定修复次序.实验证明快速修复算法显著减小了运算时间,并且修复后图像纹理更加清晰,达到了较好效果.
A rapid image inpainting algorithm based on TV model is proposed. The algorithm interpolate the damaged pixels with it＇ s neighborhood-pixel weighted mean. The weighted factors are decided by gradient mode and gradient direction of image, and the interpolating order is also decided by variance of gradient. Comparing with TV model, better inpainting results can be achieved with much less computation time and much better image texture.
