Embodiment
[0030] see Figure 1-11 , the present invention provides the following technical solutions: an anisotropic Delaunay-based water quality prediction and early warning system, including the extraction of river network information from elevation maps, the establishment of graph structures between several monitoring stations, and the establishment, training and prediction of graph convolutional networks , where the elevation map extracts the river network information, uses the Hessian Matrix (HessianMatrix) filter to enhance the river structure of the elevation map, obtains the tubular measure (Vesselness) and tubular vector field, and constructs a variational model. The original gray value of the elevation map, the tubular Combining the measure and its anisotropy, a new energy model is proposed, and the Graph-cuts algorithm is applied to segment the channel area;
[0031] The establishment of a graph structure between several of the monitoring sites is used to divide the anisotrop...
