According to piecewise constant segmentation criterion, we obtain the partial differential equation based on polynomial piecewise constant approximation.
The basic idea of the PPCA method is to transform the original image to piecewise constant image so as to make piecewise constant segmentation criterion become applicable.
The segmentation criterion is to break the minimum spanning tree edges with the largest weight, which reflect the low-cost connection between two elements.
Unlike the classical methods this technique adaptively adjusts the segmentation criterion based on the degree of variability in neighboring regions of the image.
The calculation of the normalized cross-correlation, performed within MATLAB (The MathWorks, Inc., Natick, USA) environment, allowed the identification of the Niblack segmentation criterion [ 16] as the most performing one for scaffolds S1 and S2 and the Sauvola criterion [ 17] for scaffold S3.
Many tooth segmentation methods prefer to use surface curvature when identifying potential tooth boundaries, as they follow the most widely cited mesh segmentation criterion, the minima rule, which states that human perception usually divides a surface into parts along the concave discontinuity of the tangent plane [ 3, 4].
