A new approach for digital watermarking in medical images
MetadataShow full item record
Security and hiding personal data of medical image is very critical issue in transferring medical image data from one medical center to another .In this paper, a new approach for Digital Watermarking on Medical images is proposed which worked on various requirements such as robustness and imperceptibility. In this model, image enhancement was done by SMQT based on OTSU, segmentation of the image is performed by OTSU thresholding. Then Discrete Wavelet Transform (DWT) and IDWT is used to embed and extract the watermark on and from the host image. To evaluate the performance of the proposed model, numerous attacks were performed and measured using PSNR, MSE, and CC.
