Digital Watermarking of Medical Images - Proceedings of All India Seminar on Biomedical Engineering 2012 (AISOBE-2012) - page 108

Fig. 2 Proposed method

Fig. 3 Original image

The coding for software is done in MATLAB TM and the test image used is also
the default image provided in MATLAB TM . Figure 3 shows the original image
which is digitally watermarked
Figure 3 shows the watermarked image in which patient information is hidden
in the area surrounding ROI, the figure also shows the clear difference between
ROI and the rest of the image.
Figure 4 is the reconstructed image by the same software; if the information is
preserved in watermarked image then only software can reconstruct the image. In
case of any information loss in non-ROI region software will create a deformed
image. Similarly, loss of additional parameters present in ROI region will give an
error on reconstruction.
Figure 5 shows the reconstructed image.
