Line 319 ⟶ 320:

There are some problems in BEMD and boundary extending implementation in the iterative sifting process, including time-consuming, shape and continuity of the edges, decomposition results comparison and so on. In order to fix these problems, the '''Boundary Processing in Bidimensional Empirical Decomposition (BPBEMD)''' method was created. The main points of the new method algorithm will be described next.
