Watershed Segmentation Based on Histogram Threshold and Lowest Mean Edge Value
Qian Lin, Tian Long Mu, Wei Feng Li, Xiu Lan Huang · Applied Mechanics and Materials · 2013
A novel algorithm based on gradient image histogram threshold and lowest mean edge value is proposed. Image objects are initialized using the gradient image histogram threshold and grow up using the watershed segmentation algorithm. To reduce the number of image objects, a merge method based on lowest mean edge value is proposed. The segmentation result revealed the advantage of this method in preventing over-segmentation.
