- In the present era of the digital world, digital images and videos are the main carriers of information. However, these sources of information can be easily manipulated by using readily available photo editing softwares such as Photoshop etc. Nowadays, it is possible to add or remove some important objects or features from the image without leaving any traces of tampering. Such type of forgery is called as copy move forgery in which objects from the image are copied and pasted within same image. To detect the copy move forgery in digital images have become the most hot research area nowadays. To solve the above problem, this paper proposes a hybrid method which is a combination of Dyadic Wavelet Transform (DyWT) and Scale Invariant Feature Transform (SIFT). In this method, DyWT is used to decompose image into four parts LL, LH, HL, and HH. Since LL part contains most of the information SIFT is applied on LL part to extract the features. Finally sorting algorithm RANSAC is used to match the features and to take the decision about forgery. The performance of proposed algorithm is tested on various images and the results show that algorithm works efficiently.
