摘要:... In this study, we aimed to explore different techniques in motion-compensated temporal processing of MPS images and their impact on image quality and quantitative accuracy.(#br)Material and method(#br)50 patients without known heart condition underwent gated MPS. 3D motion compensation...

摘要:Abstract(#br)In this paper, we present a motion compensation algorithm dedicated to video processing during neurosurgery. After craniotomy, the brain surface undergoes a repetitive motion due to the cardiac pulsation. This motion as well as potential video camera motion prevent a...

摘要:Abstract(#br)In this work, a robust nonrigid motion compensation approach, is applied to the compressed sensing reconstruction of dynamic cardiac cine MRI sequences. Respiratory and cardiac motion separation coupled with a registration algorithm is used to provide accurate recons...

摘要:Abstract(#br)Lock-in thermography measurements are influenced by rigid body motion of the specimen due to the mechanical loading. These motion affects asymmetries in the measured temperature fields in the vicinity of the crack. This effect can be eliminated by a motion compensation...

摘要:Abstract(#br)Recently, there has been an increasing interest in the use of spatial transformations for motion-compensated prediction. A spatial transformation is a process by which the coordinates of pixels of one image are mapped to new coordinates to form another image. There a...

摘要:Abstract(#br)This paper presents a two-stage motion compensation coding scheme for image sequences in hemodynamics. The first stage of the proposed method implements motion compensation, and the second stage corrects local pixel intensity distortions with a context adaptive linea...

摘要:Alternative fully DCT-based video codec architectures have been proposed in the past to address the shortcomings of the conventional hybrid motion compensated DCT video codec structures traditionally chosen as the basis of implementation of standard-compliant codecs. However, no ...

摘要:Abstract(#br)An inherent disadvantage of digital subtraction angiography (DSA) is its sensitivity to patient motion which causes artifacts in the subtraction images. These artifacts could often reduce the diagnostic value of this technique. Automated, fast and accurate motion compensation...

摘要:Abstract(#br)This paper presents a system for correcting motion influences in time-dependent 2D contrast-enhanced ultrasound (CEUS) images to assess tissue perfusion characteristics. The system consists of a semi-automatic frame selection method to find images with out-of-plane motion...
