A

adjacencyMatrixToTouchMatrix

Converts a adjacency matrix in a touch matrix.

averageDistanceOfNClosestPoints

Determines the average of the n closest points for every point in a distance matrix.

averageDistanceOfNFarOffPoints

Determines the average of the n far off (most distant) points for every point in a distance matrix.

averageDistanceOfTouchingNeighbors

Takes a touch matrix and a distance matrix to determine the average distance of touching neighbors for every object.

C

colorDeconvolution (Experimental)

Computes the color deconvolution of an 8bit RGB stack color image with a given 3x3 matrix of color vectors. Note: The input image has to be a stack with three z-slices corresponding to the red, green and blue channel.)

countTouchingNeighbors

Takes a touch matrix as input and delivers a vector with number of touching neighbors per label as a vector.

D

distanceMap

Generates a distance map from a binary image.

distanceMatrixToMesh

Generates a mesh from a distance matric and a list of point coordinates.

G

generateAngleMatrix (Experimental)

Computes the angle in radians between all point coordinates given in two point lists.

generateBinaryOverlapMatrix

Takes two labelmaps with n and m labels and generates a (n+1)*(m+1) matrix where all pixels are set to 0 exept those where labels overlap between the label maps.

generateDistanceMatrix

Computes the distance between all point coordinates given in two point lists.

generateDistanceMatrixAlongAxis (Experimental)

Computes the distance in X, Y or Z (specified with parameter axis) between all point coordinates given in two point lists.

generateGreyValueCooccurrenceMatrixBox (Experimental)

Takes an image and an intensity range to determine a grey value co-occurrence matrix.

generateIntegerGreyValueCooccurrenceCountMatrixHalfBox (Experimental)

Takes an image and assumes its grey values are integers. It builds up a grey-level co-occurrence matrix of neighboring (west, south-west, south, south-east, in 3D 9 pixels on the next plane) pixel intensities.

generateIntegerGreyValueCooccurrenceCountMatrixHalfDiamond (Experimental)

Takes an image and assumes its grey values are integers. It builds up a grey-level co-occurrence matrix of neighboring (left, bottom, back) pixel intensities.

generateJaccardIndexMatrix

Takes two labelmaps with n and m labels_2 and generates a (n+1)*(m+1) matrix where all labels_1 are set to 0 exept those where labels_2 overlap between the label maps.

generateNNearestNeighborsMatrix

Produces a touch-matrix where the n nearest neighbors are marked as touching neighbors.

generateProximalNeighborsMatrix

Produces a touch-matrix where the neighbors within a given distance range are marked as touching neighbors.

generateTouchCountMatrix

Takes a label map with n labels and generates a (n+1)*(n+1) matrix where all pixels are set the number of pixels where labels touch (diamond neighborhood).

generateTouchMatrix

Takes a labelmap with n labels and generates a (n+1)*(n+1) matrix where all pixels are set to 0 exept those where labels are touching.

M

matrixEqual

Checks if all elements of a matrix are different by less than or equal to a given tolerance.

maximumDistanceOfTouchingNeighbors
