Steganaliz ile bir medya dosyasındaki gizli mesajı elde etmek ya da sadece mesajın varlığını tespit amaçlanır. Literatürde medikal verilerin güvenliğini sağlamayı amaçlayan pek çok steganografi yöntemi mevcut olsa steganaliz çalışması azdır. Bu çalışmada, görüntü yöntemlerinin dayanıklılığının arttırılmasında kullanılabilecek ve görüntüde mesajların edebilecek sınıflandırıcı geliştirilmesi amaç...

Since the physical behavior of many tissues is shown to be viscoelastic, we propose a novel registration technique for medical images via physical principles of viscoelasticity. It allows the template and the target images to differ by large local deformations like viscous fluid and small local deformations like elastic solid. With an extra elastic term introduced, the proposed model constrains...

Digital image watermarking have been developed widely in recent years. One of the most important applications of digital image watermarking is medical applications. Image watermarking can be used in medical images for several purposes. It’s used to protect the patient’s information from unauthorized people. In addition, it can be used for authentication if the patient lost his/her image. Moreov...

Contrast enhancement is very useful in medical image analysis that helps the physicians for disease diagnosis. The quality of medical images affects the analysis if the contrast of the images is poor. This paper presents method to enhance the contrast with improved CNR (contrast to noise ratio).

The analysis of texture parameters is a useful way of increasing the information obtainable from medical images. It is an ongoing field of research, with applications ranging from the segmentation of specific anatomical structures and the detection of lesions, to differentiation between pathological and healthy tissue in different organs. Texture analysis uses radiological images obtained in ro...
