Detection and classification of an object is of growing concern in many application areas. Ground Penetrating Radar (GPR) data has been widely used in fields like military, archeology, and geophysical exploration and many such applications. In this paper, we present a combination of Singular Value Decomposition (SVD) approach and Blob detector for detection of buried objects from ground penetrating...
Digital image watermarking is being extensively used for protecting sensitive image data transmitted over insecure channels. Watermarks are primarily used for two fold operations, copyright protection and content authentication. Robust image watermarks are used for copyright protection and fragile watermarks used for the content authentication. In this paper fragility evaluation of a fragile image...
This paper presents an efficient method to detect Copy Move Forgery using SIFT features and the volume of these features is heavily reduced by Chan-Vese's Level Set approach. Multiple-forged object detection, invariant to scale and rotation, high speed, its simplicity in implementation and robustness are some of this method's strengths.
Digital Image Watermarking is used to hide the copyrighted information as a watermark inside a Digital image, to identify the ownership. In this paper to ensure the security watermark is first encrypted by standard A5/1 algorithm. The encrypted watermark is encoded by repetition code to provide robustness against salt and pepper noise and embedded inside the cover image by modifying the least significant...
