2DInpaint: A novel privacy-preserving scheme for image inpainting in an encrypted domain over the cloud
作者：
Highlights：
• A novel inpainting scheme which can be performed in the encrypted domain over the cloud is proposed.
• User’s image is secured into multiple encrypted shares using ramp secret sharing scheme.
• The scheme utilizes 2D-bicubic interpolation for approximating the inpainted region.
• 2DInpaint is proved to be indistinguishable theoretically and experimentally under various cryptographic attacks.
• The reconstructed results are compared with existing partial differential equation and exemplar based schemes in plain domain.
