A new watershed algorithm based on multi-scale and self-adaptive marker-extraction is proposed to overcome over-segmentation.Firstly
multiple scale filtering is executed on the V component of HSV space
and image after filtering is transformed from HSV space to RGB space.And then
multiple scale filtering is executed on image gradient.Finally
H-minima transformation is used to adaptively extract markers.At last
the watershed transformation of modified gradient is performed.The experimental results show that the proposed algorithm is obviously effective for the over-segmentation
and obtain meaningful and more reasonable regions.
