MST-triangle network construction

Construct network by combining minimum spanning tree (MST) and triangular closure.

This code is used to select interferometric pairs and construct coherent point network for multi-temporal InSAR data processing.

The proposed strategy utilizes the combination of minimum spanning tree (MST) and triangular closure to determine the pair of image/point included in the network.

The incentive behind that is to increase the total coherence of temporal and spatial networks and meanwhile to preserve redundant edges to check network consistency.

The algorithms are described in:
