BEMD and edge detection for loess shoulder-line extraction

The data in the .shp format represents the gully lines extracted using a combination of BEMD (Bidimensional Empirical Mode Decomposition) and the LOG (Laplacian of Gaussian) edge detection operator. This data is utilized for visualizing the results and conducting subsequent accuracy assessments. The two code segments provided are the primary scripts for BEMD, which facilitate the multiscale decomposition of the data.
