Automatic landmark correspondence detection for ImageJ

نویسنده

چکیده

Landmark correspondences can be used for various tasks in image processing such as image alignment, reconstruction of panoramic photographs, object recognition and simultaneous localization and mapping for mobile robots. The computer vision community knows several techniques for extracting and pairwise associating such landmarks using distinctive invariant local image features. Two very successful methods are the Scale Invariant Feature Transform (SIFT) and Multi-Scale Oriented Patches (MOPS). We implemented these methods in the Java programming language for seamless use in ImageJ. We use it for fully automatic registration of gigantic serial section Transmission Electron Microscopy (TEM) mosaics. Using automatically detected landmark correspondences, the registration of large image mosaics simplifies to globally minimizing the displacement of corresponding points. We present here an introduction to automatic landmark correspondence detection and demonstrate our implementation for ImageJ. We demonstrate the application of the plug-in on diverse image data.

Lung registration using automatically detected landmarks.

OBJECTIVES Accurate registration of lung CT images is inevitable for numerous clinical applications. Usually, nonlinear intensity-based methods are used. Their accuracy is typically evaluated using corresponding anatomical points (landmarks; e.g. bifurcations of bronchial and vessel trees) annotated by medical experts in the images to register. As image registration can be interpreted as corres...

Development and validation of a multi-step approach to improved detection of 3D point landmarks in tomographic images

We introduce a novel multi-step approach to improved detection of 3D anatomical point landmarks in tomographic images. Such landmarks serve as important image features for a variety of 3D medical image analysis tasks (e.g. image registration). Existing approaches to landmark detection, however, often suffer from a rather large number of false detections. Our multi-step approach combines an exis...

Automatic Landmark Detection in 2D images : A tree-based approach with multiresolution pixel features

In this paper, we propose a new generic landmark detection method for 2D images. Our solution is based on the use of ensembles of Extremely Randomized Trees combined with simple pixel-based multi-resolution features. We apply our method on a novel dataset of microscopic zebrafish images. This method was also tested on datasets of cephalometric images during the Automatic Cephalometric X-Ray Lan...
