In this paper, we give a short introduction to machine learning and survey its applications in radiology. We focused on six categories of applications in radiology: medical image segmentation, registration, computer aided detection and diagnosis, brain function or activity analysis and neurological disease diagnosis from fMR images, content-based image retrieval systems for CT or MRI images, an...

Dislocation is one of the major challenges in unmanned aerial vehicle (UAV) image 15 stitching. In this paper, we propose a new dynamic programming for seamlessly stitching UAV 16 images using optical flow. Our solution consists of two steps: Firstly, an image-matching algorithm 17 is used to correct the images so that they are in the same coordinate system. Secondly, a new 18 dynamic programmi...

Historical aerial images are important to retain past ground surface information. The land-use land-cover change in the past can be identified using historical aerial images. Automatic historical image registration and stitching is essential because the historical image pose information was usually lost. In this study, the Scale Invariant Feature Transform (SIFT) algorithm was used for feature ...

Image stitching is useful for a variety of tasks in vision and computer graphics. This paper presents a complete system for stitching a sequence of still images with some amount of overlapping between every two successive images. There are 3 contributions in this paper. First is a featureless registration method which handles rotation and translation between the images using phase correlation e...

The image stitching process is based on the alignment and composition of multiple images that represent parts a 3D scene. automatic construction panoramas from digital technique great importance, finding applications in different areas such as remote sensing inspection maintenance many work environments. In traditional stitching, generally performed by Levenberg–Marquardt numerical-based method...

This paper addresses the problem of stitching Giga Pixel images from airborne images acquired over multiple flight paths of Costa Rica in 2005. The set of input images contains about 10,158 images, each of size around 4072x4072 pixels, with very coarse georeferencing information (latitude and longitude of each image). Given the spatial coverage and resolution of the input images, the final stit...

OBJECTIVE Clinical documents made available for secondary use play an increasingly important role in discovery of clinical knowledge, development of research methods, and education. An important step in facilitating secondary use of clinical document collections is easy access to descriptions and samples that represent the content of the collections. This paper presents an approach to developin...

Recent stereo cameras provide reliable 3D reconstructions. These are useful for selecting ground-plane points, register them and building mosaics of cluttered ground planes. In this paper we propose a 2D Iterated Closest Point (ICP) registration method, based on the distance transform, combined with a fine-tuning-registration step using directly the image data. Experiments with real data show t...
