Fuzzy skeletonization of an image
Pattern Recognition Letters, 1989Abstract Algorithms based on minimisation of fuzzy compactness are developed wherby it is possible to obtain automatically both fuzzy and nonfuzzy skeletons of an image. Compactness measure takes into account the fuzziness in geometry of regions in an image.

Research on Skeletonization of Palmprint Image
2007 Third International IEEE Conference on Signal-Image Technologies and Internet-Based System, 2007Skeletonization is an important procedure of automated palmprint identification system based on the characteristic of minutiae. Skeleton acquired by traditional thinning algorithms will produce many spurious minutiae which are caused by spurs and misconnections between ridges.

Computing the curve-skeletons of images
International Journal of Computer Mathematics, 2008In this paper, an automatic algorithm that extracts a curve-skeleton (1-D centreline) from 2-D binary images is described. From the discretized data of the image/object, the potential field is computed resulting in a vector field defined over the entire object.

A method for parallel skeletonization of images
Proceedings., International Conference on Image Processing, 2002This paper presents a parallel thinning algorithm which processes binary images and produces the image skeletons which are either regions size independent (noise non-sensitive in small variation of shape (PSTA2)), or noise sensitive to the regions shape (PSTA1).

Imaging of Osteomyelitis in the Mature Skeleton
Radiologic Clinics of North America, 2001Diagnosis of acute osteomyelitis is often challenging but can be made by plain radiograph, bone scan, or MR imaging. This diagnosis may be more problematic in small bones, in diabetic or immunocompromised patients, those partially treated, post-traumatic, previous surgery, or with pre-existing marrow conditions and associated soft tissue infections.

Imaging in osteomyelitis in the growing skeleton
Der Orthopäde, 1997In acute osteomyelitis of childhood a rapid diagnosis and initiation of antibiotic therapy is necessary in order to prevent late sequelae. Thus, diagnostic imaging plays a crucial role. If acute osteomyelitis is suspected in a child, imaging starts with conventional radiography in order to exclude other differential diagnoses.

Distance-Driven Skeletonization in Voxel Images
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2011A distance-driven method to compute the surface and curve skeletons of 3D objects in voxel images is described. The method is based on the use of the weighted distance transform, on the detection of anchor points, and on the application of topology preserving removal operations.

Matching UAV images with image topology skeleton
2013 IEEE International Geoscience and Remote Sensing Symposium - IGARSS, 2013We address the problem of efficient image matching for large, highly redundant photo collections with highly complex topologies, such as photos acquired by unmanned aerial vehicles (UAV), focusing on disaster monitoring. Our approach conducts a skeleton graph which simplifies the image topology with the consideration of image importance and topological

Image Skeletonization Based on Curve Skeleton Extraction
2011Skeletonization is a transformation of an object in a digital image into a simplified representation of the original object. The skeleton of an image object is an abstraction of the original object which largely preserves the extent and connectivity of the original region while throwing away most of the boundary and interior pixels.

Simplifying curve skeletons in volume images
Computer Vision and Image Understanding, 2003Summary: The curve skeleton of a 3D solid object provides a useful tool for shape analysis tasks. In this paper, we use a recent skeletonization algorithm based on voxel classification that originates a nearly thin, i.e., at most two-voxel thick, curve skeleton. We introduce a novel way to compress the nearly thin curve skeleton to one-voxel thickness,
