-/** We consider an image, i.e. a rectangular arrangement of pixels, of given
- * height and width. Every pixel has a specific value (e.g., grey value) given
- * by the 'values' array as concatenation of all rows. We add every pixel as
- * vertex with its value as simplex value. We further triangulate the resulting
- * rectangular latice as a grid graph together with south-west to north-east
- * edges for each of the small squares of the grid graph. Finally the resulting
- * triangles are added. For all non-vertex simplices the maximum of its
- * vertex-values is used as its value. The first pixel is considered to be at
- * bottom-left. */
