Skeletonization of labeled gray-tone images
Image and Vision Computing, 2005A gray-tone image including perceptually meaningful elongated regions can be represented by a set of line patterns, the skeleton, consisting of pixels having different gray-values and mostly placed along the central positions of the regions themselves.

Image warping refers to the 2D resampling of a source image onto a target image. Despite the variety of techniques proposed, a large class of image warping problems remains inadequately solved: mapping between two images which are delimited by arbitrary, closed, planar curves, e.g., handdrawn curves.

Magnetic resonance imaging of the immature skeleton
Acta Radiologica, 2013Magnetic resonance (MR) is unique in its ability to allow assessment of bone marrow, epiphyseal, physeal, and articular cartilage as well as tendons and ligaments. An understanding of skeletal maturation and the accompanying changes on MR is of utmost importance in pediatric radiology.

Skeletonization for fuzzy degraded character images
IEEE Transactions on Image Processing, 1996Most skeletonization algorithms are operated on binary images. To avoid information loss and distortion, a topography-based approach is proposed to apply directly on fuzzy or gray scale images. A membership function is used to indicate the degree of membership of each ridge point with respect to the skeleton. Significant ridge points are linked to form

The role for PET imaging of the skeleton is evolving. It is possible that 18F-fluoride PET may have incremental value in detecting bone metastases over conventional bone scintigraphy, but this has yet to be established. A role may also exist for quantitative studies using 18F-fluoride PET for research or clinical applications where there is a need to ...

A Survey on Skeletons in Digital Image Processing
2009 International Conference on Digital Image Processing, 2009An image is digitized to convert it to a form which can be stored in a computer's memory or on some form of storage media such as a hard disk or CD-ROM. Once the image has been digitized, it can be operated upon by various image processing operations like enhancement, restoration, reconstruction, compression.

Imaging of Diseases of the Axial and Peripheral Skeleton
Radiologic Clinics of North America, 2008Musculoskeletal complaints are common in the elderly population. The main concerns in geriatric orthopedics are the increased incidence of trauma, degeneration, and malignancy, commonly compounded by comorbidities and the effects of ageing. Imaging of common and important diseases of the axial and peripheral skeleton in the elderly is reviewed in this ...

Morphological skeletonization for medical image compression
[1992] Proceedings Fifth Annual IEEE Symposium on Computer-Based Medical Systems, 2003The authors introduce a lossless data compression technique based on the morphological skeleton representation. Mathematical morphology is a methodology for image analysis which provides a means for describing the geometrical structure of an image quantitatively.

Skeletons are “compact” representations of the original objects, which are useful for many visualization tasks including medical imaging, computer graphics, computer-aided design. We introduce the basic concepts and properties of 3D skeletonization in this paper. Then we present the techniques of 3D skeletonization, especially in thinning.

Continuous Skeletons from Digitized Images
Journal of the ACM, 1969An algorithm for the determination of the skeleton of a polygonal figure is presented. The propagation of the figure contour is simulated analytically. All skeleton branch points are obtained, in an order which depends on their distance from the contour, together with the equations of the skeleton branches connecting them.
