4、embedded bits should be large enough for the clinicians to write their diagnosis report. Some of the available watermarking techniques used for embedding text information into medical images can be found in [2,3,4].Po

5、pular Benchmarks: The important available benchmarks are Stirmark, Checkmark, Optimark and Certimark. All the these benchmarks share the common inefficiency of providing a platform for evaluating all kinds of image water

6、marking methods. This makes a room for research on devising a benchmark for all kinds of image watermarking.3. A NOVEL BENCHMARK FOR MEDICAL IMAGE WATERMARKINGAn ideal benchmarking procedure should involve examining th

7、e set of mutually dependent parameters of the watermarking system and it should clearly optimize the trade off between various constraints of watermarking. Various performance metrics are used to evaluate these parameter
