Dissertation
Content-based video copy detection using multimodal analysis
TL;DR: This thesis presents a multimodal framework for matching video sequences using a three-step approach, and shows that the proposed method performs better than most of the state-of-the-art techniques, in terms of both effectiveness and efficiency.
Parallel implementation of spread spectrum based oblivious visual watermarking using efficient DWT
Ali Hassan,M. Shamim Baig +1 more
TL;DR: A spread spectrum (SS) based watermarking technique is presented in this paper which adds watermark in the carrier digital video obliviously using efficient implementation of Discrete Wavelet Transform in parallel computing environment.

Image digital watermarking based on a novel clock-controlled generator
TL;DR: Theoretical analysis results show that the new clock-controlled sequence (NCCS) with large period and high linear complexity is proposed, and the image digital watermarking algorithm would be developed in terms of NCCS.

Robust Video Watermarking of Hybrid based techniques
TL;DR: Experimental results show that the proposed system achieves good imperceptibility and high resistance against various attacks.
Using biasoptimiazation for reversible data h iding using image interpolation
TL;DR: In this article, the authors proposed a reversible data hiding method in the spatial domain for compressed grayscale images by embedding secret bits into a compressed thumbnail of the original image by using a novel interpolation method and the Neighbour Mean Interpolation (NMI) technique.

Secure spread spectrum watermarking for multimedia
TL;DR: It is argued that insertion of a watermark under this regime makes the watermark robust to signal processing operations and common geometric transformations provided that the original image is available and that it can be successfully registered against the transformed watermarked image.

Techniques for data hiding
TL;DR: This work explores both traditional and novel techniques for addressing the data-hiding process and evaluates these techniques in light of three applications: copyright protection, tamper-proofing, and augmentation data embedding.

A digital watermark
TL;DR: The paper discusses the feasibility of coding an "undetectable" digital water mark on a standard 512/spl times/512 intensity image with an 8 bit gray scale, capable of carrying such information as authentication or authorisation codes, or a legend essential for image interpretation.
Journal ArticleDOI
Image coding based on a fractal theory of iterated contractive image transformations
TL;DR: The author proposes an independent and novel approach to image coding, based on a fractal theory of iterated transformations, that relies on the assumption that image redundancy can be efficiently exploited through self-transformability on a block-wise basis and approximates an original image by a Fractal image.
