Converts a adjacency matrix in a touch matrix.

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

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

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

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

Generates a distance map from a binary image.

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

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.

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

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

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.

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.

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.

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).

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.

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

Takes a touch matrix and a vector of values to determine the maximum value among touching neighbors for every object.

Takes a touch matrix and a vector of values to determine the mean value among touching neighbors for every object.

Takes a touch matrix and a vector of values to determine the median value among touching neighbors for every object.

Determine the n point indices with shortest distance for all points in a distance matrix.

Determine the n point indices with shortest distance for all points in a distance matrix.

Determines neighbors of neigbors from touch matrix and saves the result as a new touch matrix.

Sets all pixel values a of a given image A to a constant value v in case its coordinates x == y.

Sets all pixel values a of a given image A to a constant value v in case its coordinates x > y.

Sets all pixel values a of a given image A to a constant value v in case its coordinates x < y.

Determine the shortest distance from a distance matrix.

Takes a touch matrix and a vector of values to determine the standard deviation value among touching neighbors for every object.

Converts a touch matrix in an adjacency matrix

Takes a pointlist with dimensions n*d with n point coordinates in d dimensions and a touch matrix of size n*n to draw lines from all points to points if the corresponding pixel in the touch matrix is 1.

Takes a point list image representing n points (n*2 for 2D points, n*3 for 3D points) and a corresponding touch matrix , sized (n+1)*(n+1), and exports them in VTK format.
