where $R$ is the number of regions in the segmented image, $A_i$ is the area, or the number of pixels of the ith region $i$, and $e_i$ the color error of region $i$. e is defined as the sum of the Euclidean distance of the color vectors between the original image and the segmented image of each pixel in the region, while $R(A_i)$ represents the number of regions having an area equal to $A_i$.

"This contrast takes into account the internal and external contrast of the regions measured in the neighborhood of each pixel"
ImageSegmentationEvaluation.boundary_map
— Method"
function boundary_map(seg::Matrix{T}) where T<:Integer
From a segmentation, compute a binary boundary map with 1 pixel wide boundaries. The boundary pixels are offset by 1/2 pixel towards the origin from the actual segment boundary.
ImageSegmentationEvaluation.LineNormals2D
— Methodfunction LineNormals2D(vertices)
This function calculates the normals, of the line points using the neighbouring points of each contour point, and forward an backward differences on the end points
ImageSegmentationEvaluation.color_error_sum
— Method´´´julia function colorerrorsum(image::Matrix, segments::Matrix{Integer) ´´´ Computes $\sum\limits_{i=1}^R \dfrac{e_i^2}{\sqrt{A_i}}$ where $R$ is the number of regions in the segmented image, $A_i$ is the area, or the number of pixels of the ith region $i$, and $e_i$ the color error of region $i$. e is defined as the sum of the Euclidean distance of the color vectors between the original image and the segmented image of each pixel in the region.
ImageSegmentationEvaluation.relabel
— Method"
function relabel(c1::Matrix}, part_bimap=Dict{Integer,Integer}()) where T<:Integer
It relabels a partition in scanning order. Bimaps are the look up tables of the relabeling.
