Authors: Dr. Mohiy hadhoud, Dr. Abdalhameed shaalan, Miss hanaa abdalaziz
Abstract:
A quantization based method for watermarking digital images is presented here. This scheme inserting a watermark bit into wavelet coefficients of high magnitude (LH3-HL3). Also, this watermarking technique is blind (i.e., neither the original image nor any side information is required in the recovery process) as well as being very computationally efficient. This watermarking algorithm combines and adapts various aspects from more than one existing watermarking method. Results show that the newly presented method improves upon the existing techniques.
