Abstract:
To solve the problem of copyright protection and identification in spreading images in Internet and other digital media,a bi-level watermark is embedded in the image and extracted by a blind algorithm based on LabVIEW.This system is composed of embedding and extracting watermark.An image is read via the ’Read BMP File’ node that has integrated into LabVIEW.Using discrete wavelet transform to decompose the original image,and via the human visual peculiarity a watermark is embedded in the intermediate frequency of original image.The knowledge of the minimum risk test by hypothesis is used to extract the watermark.Experimental results show that the proposed algorithm is strongly robust to the geometry distortion and the signal processing.
