The large variety of signal processing tools available today permits to anyone to easily modify digital multimedia objects like images without leaving any perceptible trace of the modifications. Therefore the digital image authentication becomes a very important issue. In this paper we propose a semi-fragile image watermarking scheme for image authentication and tamper localization. The watermark...
This paper proposes the performance of a new algorithm for vehicles recognition system. This recognition system is based on extracted features on the performance of image's curvelet transform and achieving standard deviation of curvelet coefficients matrix in different scales and various orientations. The curvelet transform is a multiscale transform with frame elements indexed by location, scale and...
