A Watermarking of Medical Image-New Approach Based On Multi-Layer Method
In order to contribute to security sharing and transmission of
medical images, this paper propose a new approach for
Watermarking image based on the techniques of Code Division
Multiple Access (CDMA), Discrete Wavelet transform (DWT)
and Error Correcting Code (ECC). The motivation of this
approach is to improve the quantity of data integration with the
conservation of the image visual quality. Therefore, this work
permits to the user the capacity to correct the possible alterations
if it exists. IRM and Echographic medical image are used to
experiment this approach.
