Nowadays, the digital copyrights are the common concern in the Multimedia Digital production industry and these copyrights apply various watermarking techniques. In this paper we present a method for a robust watermarking insertion in a video frame. The proposed method works on the uncompressed video based on the spread spectrum communication. The researchers applied the technique in the discrete...
H.264/AVC is the latest video coding standard from ITU-T. It provides superior and efficient video coding at low bit rates. Flexible macroblocks ordering (FMO) is an error-resilient tool included in H.264/AVC. In this paper, a novel technique for adaptive classification of macroblocks into two slice groups using FMO method is proposed. With our adaptive macroblocks allocation map, simulation results...
A new method for digital video watermarking is presented in this paper. For data embedding we use 3-D ridgelet domain introduced by Helbert. The redundancy of this transform is substantial, so extraction of the hidden data is impossible in this domain. To overcome this problem, we introduce a modified ridgelet transform with little redundancy, and embed watermark in this domain. Experimental results...
This paper presents a blind digital video watermarking scheme, which is especially robust to camcorder recording attacks and also to a variety of common video processing and geometric distortions. Using the fact that nearby frames of a video sequence are quite similar, the method embeds the watermark by temporal modulation of the frames. The watermark pattern used in modulation is generated based...
Image line segment feature is sparse and directional, and can facilitate the analysis of some specific geometric features and patterns. A novel vehicle target motion estimation and recognition method based on target edge line segment feature is introduced. This method includes a series of algorithms using segments as the basic elements of calculation. At first the definition of the similarities of...
