Title
Fragile watermarking for color image recovery based on color filter array interpolation
Abstract
In this paper, a novel fragile watermarking method is proposed for color image recovery via color filter array interpolation. First we turn a color image into a grey image by color sampling in the form of Bayer patterns. Data of the grey image which is reordered as reference bits are then embedded into the original image along with some authentication bits generated from the image. After the watermarked image is received, authentication bits are extracted to identify which regions are tampered. When the image is detected to be tampered, extracted reference bits are used to reconstruct a color image by color filter array interpolation, which is then used to recover the content of the tampered regions. Experiments show this method has good recovery ability.
