Fast Abdominal Medical Image Registration Based on Modified SIFT
نویسندگان
چکیده
SIFT is an excellent descriptor to features in medical images. However, the algorithm to achieve SIFT is tedious and takes a long time. To cope with this, we combined image integration and image region partition and proposed a modified SIFT descriptor capable of describing the global energy information of the image. We further proposed a spatial SIFT -oriented non-rigid registration model. Experimental results indicated that fast and accurate registration could be achieved with this method.

3D ultrasound volume stitching using phase symmetry and harris corner detection for orthopaedic applications
Stitching of volumes obtained from three dimensional (3D) ultrasound (US) scanners improves visualization of anatomy in many clinical applications. Fast but accurate volume registration remains the key challenge in this area.We propose a volume stitching method based on efficient registration of 3D US volumes obtained from a tracked US probe. Since the volumes, after adjusting for probe motion,...
متن کاملMedical image registration using machine learning-based interest point detector
This paper presents a feature-based image registration framework which exploits a novel machine learning (ML)based interest point detection (IPD) algorithm for feature selection and correspondence detection. We use a feed-forward neural network (NN) with back-propagation as our base ML detector. Literature on ML-based IPD is scarce and to our best knowledge no previous research has addressed fe...
متن کاملCombining Mutual Information and Scale Invariant Feature Transform for Fast and Robust Multisensor Sar Image Registration
The Scale Invariant Feature Transform (SIFT) operator's success for computer vision applications makes it an attractive solution for the intricate feature based SAR image registration problem. For SAR images, SIFT feature matching results into lot of false alarms. To overcome the mentioned problem, we propose to use mutual information (MI) along with the SIFT operator for SAR image registration...

Super-resolution (SR) aims to overcome the ill-posed conditions of image acquisition. SR facilitates scene recognition from low-resolution image(s). Generally assumes that high and low resolution images share similar intrinsic geometries. Various approaches have tried to aggregate the informative details of multiple low-resolution images into a high-resolution one. In this paper, we present a n...
متن کاملModified RANSAC for SIFT-Based InSAR Image Registration
Abstract—In this paper, we propose a modified version of the Random Sample Consensus (RANSAC) method for Interferometric Synthetic Aperture Radar (InSAR) image registration based on the ScaleInvariant Feature Transform (SIFT). Because of speckle, the “maximization of inliers” criterion in the original RANSAC cannot obtain the optimal results. Since in InSAR image registration, the registration ...
