Abstract
With the advancement in technology, it becomes easy for some individuals to use digital data without the permission of the owner. To increase authentication and security of copyrights, digital watermarking was introduced. Medical videos contain very significant information about the condition of the patient. A good watermarking scheme should always contain very less distortion. Videos generally contain huge temporal redundancy, which demands the use of motion vector estimation technique in order to remove the temporal redundancy. In this work, an image was watermarked inside the motion vector of two consecutive frames of an echo-cardiograph video. Quality analysis of the recovered video with the original video proves the robustness of the proposed scheme.Keywords
