| Image Watermarkıng Wıth Usıng Tıme-Frequency Approach
In the past decade digital media are replacing analog media with the development of internet and digital technology. It is true that digital media offer many benefits but also it brings some problems. For example digital content can be easily copied and distributed without permission from the owner of the content.This has led strong demand for copyright protection technics. To solve this problem digital watermarking can be used.
In this thesis, the historical development of watermarking of digital signals is briefly given and after that time-frequency baseb watermarking technnics like Wigner Distribution, Wavelet Distrubution are researched.
At the end of the thesis, a simulation application is done in the MATLAB programme. This application gives an idea of embedding a watermark in an image and detect it back. Lots of attacks have been applied to the image and reserched with graphics if we can detect the watermark or not.
