A Watershed Image Segmentation Algorithm Based on Self-adaptive Marking and Interregional Affinity Propagation Clustering
The watershed algorithm can conduct region-based image segmentation effectively and accurately
but it tends to cause over-segmentation.To tackle the above mentioned problem
an improved watershed algorithm is proposed
as follows:first of all
the color gradient is computed using spectrum envelope filtered color image
based on which
regions with minimum gradient are marked using self-adaptive H-minima transformation method.Then
the watershed transform is applied to segment the marked gradient image.Finally
affinity propagation clustering is adopted to merge the regions segmented by the watershed transform
using color moments computed on each local region
to get the final segmentation result.Experiments conducted on public available datasets demonstrate the adaptability and robustness of proposed algorithm
compared with the relative state-of-the-art methods.The proposed method can solve the over-segmentation problem well and get accurate results.
