EVALUATING THE PERFORMANCE OF MEDICAL IMAGES IN A WATERMARKING APPLICATION
Shehu Ayuba · 2014
This paper captures how different types of images perform differently as a result of their variation of sources or means of capture using a particular watermarking application. The performance of the watermarking application was measured using the standard quality metrics on different sets of images (Angiogram, CT and Ordinary Test Images). The performance evaluation metric employed in this research is Structural Similarity Index Measure (SSIM) (Ayuba, 2013), which yielded some sets of result for Angiogram, CT and Test Images. A statistical analysis of Variance was conducted to determine which set of images are the most suitable for the application. The results show that, similarity of original and watermarked image is higher using Angiogram followed by CT image while the least among them is the Test Image. Angiogram and CT images are more suitable for the watermarking application.
