Paper Abstract

In this paper, real-time region hierarchy, contour extraction, and smoothing algorithms are discussed. The hierarchical partitioning method produces the region specifics, median, lowest and highest values, size, and the locations of the pixels for each region. Hierarchical partitioning is achieved using the 'pixel value proximity of intensity' criterion. The partitioning algorithm employs a real-time algorithm that computes the region specifics. The proposed contour extraction method repeatedly selects an optimal pixel among many neighbor pixels until no further eligible pixel is found on the given contour. The result of contour extraction implementation is a boundary with many rough edges. Smoothing is achieved by altering the frequency for which directional values are calculated. The hierarchical partitioning, contour extraction, and smoothing algorithms have been implemented and their results are discussed.
