Spatio-Temporal Continuous Wavelet Transforms for Motion-Based Segmentation in Real Image Sequences
The purpose of this paper is to develop a motionbased segmentation for digital image sequences that is based on continuous wavelet transform. Continuous wavelet transform allows e...

Global Localization and Relative Pose Estimation Based on Scale-Invariant Features
The capability of maintaining the pose of the mobile robot is central for basic navigation and map building tasks. In this paper we describe a vision-based hybrid localization sch...

Augmenting text document by on-line learning of local arrangement of keypoints
We propose a technique for text document tracking over a large range of viewpoints. Since the popular SIFT or SURF descriptors typically fail on such documents, our method conside...

Bivariate Feature Localization for SIFT Assuming a Gaussian Feature Shape
In this paper, the well-known SIFT detector is extended with a bivariate feature localization. This is done by using function models that assume a Gaussian feature shape for the de...

Continuity Order of Local Displacement in Volumetric Image Sequence
Abstract. We introduce a method for volumetric cardiac motion analysis using variational optical flow computation involving the prior with the fractional order differentiations. ...
