Abstract

This article presents the results of the implementation and evaluation of the most common algorithms on medical images watermarking. The algorithms were modified to bring them to its maximum insertion capacity, and also modified to work with images of more than 8 bits, due to radiological images work with 8, 12 and 16 depth bits in gray scale depending on the study type. The algorithms were tested with a set of DICOM images which have been left available online. The DICOM watermarked images were tested with common attacks to evaluate the behavior of the algorithms. Conclusions were drawn based on the algorithms performance applied to medical images.
