Effect of Watermarking on Diagnostic Preservation of Atherosclerotic Ultrasound Video in Stroke Telemedicine

摘要: Embedding of diagnostic and health care information requires secure encryption watermarking. This research paper presents a comprehensive study for the behavior some well established watermarking algorithms in frequency domain preservation stroke-based parameters. Two different sets namely: two correlation-based (binary logo hiding) singular value decomposition (SVD)-based (gray are used embedding ownership logo. The parameters atherosclerotic plaque ultrasound video (a) bulb identification recognition which consists identifying edge points far near carotid walls; (b) diameter; (c) lumen thickness all along artery. tested data set movies taken under IRB protocol from University Indiana Hospital, USA-AtheroPoint™ (Roseville, CA, USA) joint pilot study. ROC (receiver operating characteristic) analysis was performed on detection process that showed an accuracy sensitivity 100 % each, respectively. (DPsystem) SVD-based approach above 99 with PSNR (Peak signal-to-noise ratio) 41, ensuring retention parameter devalorization as effect Thus, fully automated proposed system proved to be efficient method stroke application.
