The concept of high-order motion compensation is introduced. It is argued that in hybrid video coding, motion-compensated prediction has to be viewed as a source coding problem with a delity criterion. Based on our considerations, various high-order motion compensation approaches are presented that achieve signi-cantly improved video coding results. The designed motion-compensated predictors ac...

In active vision scenarios, the motion of the observer induces an apparent motion in the image plane. One approach for camera motion compensation is the use of panoramic images, representing the scene at the different positions of the camera. In this work, an approach to build spherical panoramic views from a pan-tilt camera is described, which is based on background updating techniques. Intere...

In this study, we analyze the balance of quadruped walking robots. For this purpose, a simplified polygonal model of a quadruped walking configuration is considered. A boundaryrange-based balance margin is used for determining the system stability of the polygonal walking configuration considered herein. The balance margin enables the estimation of the walking configuration’s balance for effect...

Automated algorithm configuration procedures play an increasingly important role in the development and application of algorithms for a wide range of computationally challenging problems. Until very recently, these configuration procedures were limited to optimising a single performance objective, such as the running time or solution quality achieved by the algorithm being configured. However, ...

A new method of nonstationary signal analysis, called time-correlation analysis (TCA), is applied to a class of nonstationary random signals containing time distortion. The method reveals a relationship between the TCA summary statistics and the distortion and leads to two nonparametric estimators for the distortion function. An example is given that demonstrates the application of the TCA meth...

This paper is concerned with the estimation of the motions and the segmentation of the spatial supports of the different layers involved in transparent X-ray image sequences. Classical motion estimation methods fail on sequences involving transparent effects since they do not explicitly model this phenomenon. We propose a method that comprises three main steps: initial blockmatching for two-lay...

A motion compensation method for thermoelastic stress analysis (TSA) is described that uses digital image correlation (DIC) to capture the displacement field on the surface of the specimen. The displacement field is used to correct the infrared (IR) images to remove the effect of the motion of the specimen from the TSA. As the DIC displacements are obtained with a relatively high spatial resolu...

Dynamic contrast-enhanced MRI of the breast (DCE-MRI) is widely used for detection and quantification purposes of breast cancer. The particular acquisition procedure of DCE-MRI over time leads to motion artifacts which distort analysis results. In this work we examine two criteria for a segmentation approach to separate areas affected by motion artifacts from properly perfused regions. By appli...

This work describes a method for real-time motion detection using an active camera mounted on a padtilt platform. Image mapping is used to align images of different viewpoints so that static camera motion detection can be applied. In the presence of camera position noise, the image mapping is inexact and compensation techniques fail. The use of morphological filtering of motion images is explor...

This study proposes a real-time video stabilization method to eliminate unwanted vibration, preserve the intended movement of camera, and improve the stability of the captured video sequence. The proposed method uses a functional neural fuzzy network to learn the characteristics of different vibrations and then choose the adequate compensation weight for two different methods to calculate the c...
