Geometrically invariant watermarking: synchronization through circular Hough transform
This paper addresses a geometrically invariant watermarking method for digital images. Most previous watermarking algorithms perform weakly against geometric distortions, which des...

Video Stabilization For A Hand-held Camera Based On 3d Motion Model
In this paper, a video stabilization technique is presented. There are four steps in the proposed approach. We begin with extracting feature points from the input image using the ...

Contour Retrieval and Matching by Affine Invariant Fourier Descriptors
In the image plane, a 3 Dimensional movement of planar rigid object can be represented satisfactory by an affine motion of his boundary (the exterior contour) which we assume to b...

Efficient Non-Consecutive Feature Tracking for Structure-from-Motion
Abstract. Structure-from-motion (SfM) is an important computer vision problem and largely relies on the quality of feature tracking. In image sequences, if disjointed tracks caused...

Multisubject Non-rigid Registration of Brain MRI Using Intensity and Geometric Features
In this article we merge point feature and intensity-based registration in a single algorithm to tackle the problem of multiple brain registration. Because of the high variability ...
