TLDR
An analysis of feature-based geometry invariant watermarking algorithms through the lens of segmentation based feature point extractors and triangulation based elementary patch formations.Abstract:
In this paper, we present an analysis of feature-based geometry invariant watermarking algorithms. A discussion of the requirements on each building block is followed by potential solutions to meet these requirements. Furthermore, we present theoretical and practical limitations of these solutions via examples. In particular, segmentation based feature point extractors and triangulation based elementary patch formations are evaluated.read more

Digital image watermarking
Martyn Gilbert,Keith Wang +1 more
TL;DR: In this paper, a method of digital watermarking was proposed, in which the watermark is embodded into a first image and it is subsequently attempted to identify the digital watermarks in a second digital image.

A Image Digital Watermarking based on DWT in Invariant Wavelet Domain
TL;DR: An improved invariant wavelet that is better than the bilinear interpolation is presented, and a novel blind image watermarking algorithm of scalar costa system based on DWT in the rotation- and scale-and translation-(RST) moment invariants wavelet, i.e. RSTMIW domain is designed.

A Combined Corner and Edge Detector
Chris Harris,Mike Stephens +1 more
TL;DR: The problem the authors are addressing in Alvey Project MMI149 is that of using computer vision to understand the unconstrained 3D world, in which the viewed scenes will in general contain too wide a diversity of objects for topdown recognition techniques to work.

Rotation, scale and translation invariant spread spectrum digital image watermarking
TL;DR: In this paper, a Fourier-Mellin-based approach is used to construct watermarks which are designed to be unaffected by any combination of rotation and scale transformations, and a novel method of CDMA spread spectrum encoding is introduced which allows one to embed watermark messages of arbitrary length and which need only a secret key for decoding.
