One of the major issue is its high time complexity. A new gradient-liked approach to mimic similar spatial data decomposition results with more than 10x speedup. The GPGPU version of our approach can reach 500x speedup. Our novel approach use gradient-liked operator to evaluate the spatial frequency on different radius and integral the gradient result to spatial frame which is similar to BIMFs of MEEMD.
