| description |
Digital watermarking is distinctive depending on
the techniques used and its intended applications. This
paper concentrates on invisible digital image
watermarking using discrete wavelet transform. The
work flow involves watermark embedding, attacks and
watermark extraction. Two methods are proposed and
analyzed to imply the imperceptibility and robustness,
among the most important criteria of digital
watermarking, using three types of attacks – JPEG
compression, blurring and histogram equalization. The
results are compared through subjective visual
inspections and calculative measurements using PSNR
for watermark imperceptibility and SSIM Index for
watermark robustness. |
