Boundary Estimation from Intensity/Color Images with Algebraic Curve Models
A new concept and algorithm are presented for noniterative robust estimation of piecewise smooth curves of maximal edge strength in small image windows – typically  ¢¡£  to...

Squaring the circle: An algorithm for generating polyhedral invariant sets from ellipsoidal ones
This paper presents a new (geometrical) approach to the computation of polyhedral (robustly) positively invariant (PI) sets for general (possibly discontinuous) nonlinear discrete...

FOCUS: Searching for Multi-colored Objects in a Diverse Image Database
We describe a new multi-phase, color-based image retrieval system, FOCUS Fast Object Color-based qUery System, with an online user interface which is capable of identifying mult...

Robust perceptual image hashing via matrix invariants
In this paper we suggest viewing images (as well as attacks on them) as a sequence of linear operators and propose novel hashing algorithms employing transforms that are based on ...

Robust Homography Estimation from Planar Contours Based on Convexity
Abstract. We propose a homography estimation method from the contours of planar regions. Standard projective invariants such as cross ratios or canonical frames based on hot points...
