Image coding through skeletonization

Proceedings of the 1992 South African Symposium on Communications and Signal Processing, 2003
A new technique for the compression of grey-level images is evaluated and slightly improved. The technique is based on the decomposition of an image into its bit-maps whereafter each bit-map is coded by representing it by its skeleton, a thinned version of the bitmap, which exactly describes its shape. >

Skeleton based image encryption

Proceedings of the IEEE 12th Signal Processing and Communications Applications Conference, 2004., 2004
As a result of the increase in digital image transfer and the systems used for digital image transfer becoming of such importance as to matter commercially, methods of coding are applied in digital data transfer. As the digital data transfer is a simultaneous process, it requires fast working coding and decoding algorithms.

On extracting skeletons from binary 3D images

2017 International Conference on Systems, Signals and Image Processing (IWSSIP), 2017
This paper explores the subject of extracting skeletons from 3D binary images. It draws attention to the flaws found in the available skeletonization implementations. The most popular algorithm devised by Lee, Kashyap and Chu is analyzed. It is shown that despite good results, some aspects of said algorithm can be further improved upon.

Image coding by morphological skeleton transformation

1993
Mathematical morphology operations are becoming increasingly important for analysing images. Binary morphological operations of dilation and erosion have been successfully extended to gray-scale image processing. This paper presents the results of a study on the use of morphological set operations to represent and encode a discrete binary and gray ...

Imaging the Skeleton and the Great Vessels

1999
Abstract Radiographic examinations of lesions of tuberous sclerosis complex (TSC) have always been an important ingredient in the assessment of patients afflicted with this disease. In this chapter the classic radiographic features in the skeleton are reviewed.

The Imaging of Injuries to the Immature Skeleton

2009
In children, the types of traumatic accidents, the patterns of injury, and the imaging findings change dramatically with age. The types of injuries change as the activities become more complex as children grow older: infants have mostly inflicted injuries, toddlers have fractures related to early walking, young children are either involved in car vs ...

Skeletonization on quadtree represented images

2000
Summary: The most frequent method to represent a digital image is the pixel-pixel type representation. Because of this, most image processing algorithms operate on pixel-pixel type images. Accordingly, few years ago the interest arised to develop image processing algorithms, which operate on some special representation known from the literature.
