Segmentation of edges into lines and arcs

Image and Vision Computing, 1989
Abstract A long standing problem in computer vision is the extraction of meaningful features from images. This paper describes a method of segmenting curves in images into a combination of circular arcs and straight lines. This uses a recursive algorithm that first analyses lists of connected edge points and finds a polygonal description, and then ...

Line segmentation of Ottoman documents

2012 20th Signal Processing and Communications Applications Conference (SIU), 2012
Many researches and historians from all around the world are interested in historical Ottoman archives. However, translation of these documents requires competent historians which is not a feasible method in terms of time and cost. Thus, automatic translation of these documents are required.

Laser Line Segmentation with Dynamic Line Models

2011
Model based segmentation methods make use of a priori knowledge of the object to improve the segmentation results. Taking advantage of global information makes these methods less sensitive to local interferences like noise or line gaps. Laser lines from optical sensors are deformed due to the geometry of the measured object.

On-Line Handwritten Documents Segmentation

Ninth International Workshop on Frontiers in Handwriting Recognition, 2004
This work concerns note-taking applications. It deals with poorly structured on-line handwritten documents segmentation such as pages of handwritten notes. We extend an existing system based on probabilistic feature grammars. The probabilistic nature of this system allows considering lots of segmentation hypothesis, which is an advantage for poorly ...

On cellular straight line segments

Computer Graphics and Image Processing, 1982
Summary: We discuss a scheme for digitizing curves that is consistent with a scheme for digitizing regions. It is shown that the cellular image of a region is determined by the cellular image of its boundary by the scheme. It is proved that the chord property is a necessary and sufficient condition for a cellular arc to be a cellular straight line ...
