Flow chart of the main part of the Misty Mountain program. IDIM - dimension of the data space. N - the number of equidistant meshes along each coordinate for creating optimal histogram. LEVELMAX - highest frequency of the histogram. LEVEL - frequency where the actual cross section is created. NCL - actual number of (major and small) histogram peaks. NSTRA and NSTRB - matrices of labeled aggregates of two consecutive cross sections. NSTRF - structure matrix that stores the largest separate aggregates belonging to the major peaks (see e.g. colored aggregates in Figure 1d-j).
