Segmentation of Plane Curves
August 1974 (vol. 23 no. 8)
pp. 860-870
T. Pavlidis, Department of Electrical Engineering and Computer Science Laboratory, Princeton University
Piecewise approximation is described as a way of feature extraction, data compaction, and noise filtering of boundaries of regions of pictures and waveforms. A new fast algorithm is proposed which allows for a variable number of segments. After an arbitrary initial choice, segments are split or merged in order to drive the error norm under a prespecified bound. Results of computer experiments with cell outlines and electrocardiograms are reported.
Index Terms:
Boundary segmentation, data compaction, feature extracton, pattern recognition, piecewise functional approximation, polygonal contours, waveform segmentation.
