The Zernike polynomials are a complete set of continuous functions orthogonal over a unit
circle. Since first developed by Zernike in 1934, they have been in widespread use in many …

The illegal distribution of a digital movie is a common and significant threat to the film
industry. With the advent of high-speed broadband Internet access, a pirated copy of a …

This paper proposes a forensic technique to localize duplicated image regions based on
Zernike moments of small image blocks. We exploit rotation invariance properties to reliably …

As forgeries have become popular, the importance of forgery detection is much increased.
Copy-move forgery, one of the most commonly used methods, copies a part of the image …

Some research progress has been made on fractional-order continuous orthogonal
moments (FrCOMs) in the past two years. Compared with integer-order continuous …

The existing watermarking algorithms invariant wavelet domain are weak at resisting
geometric attacks and have small embedding capacities. In this paper, a robust double …

This paper introduces a set of 2D transforms, based on a set of orthogonal projection bases,
to generate a set of features which are invariant to rotation. We call these transforms Polar …

Cover-lossless robust watermarking is a new research issue in the information hiding
community, which can restore the cover image completely in case of no attacks. Most …

Recognizing the desired herb among thousands of herbs is an exhausting and time-
consuming practice. Hence, herbs identification via a vision system is beneficial since the …

We present the H3 layout technique for drawing large directed graphs as node-link
diagrams in 3D hyperbolic space. We can lay out much larger structures than can be …
