The standard stipulates that PU can be divided into TUs in the form of a quadtree
, and TUs share a prediction mode in the same PU.

On this basis, Needell and Vershynin  proposed the regularized orthogonal matching pursuit (ROMP) method; Scholefield and Dragotti  used a sparse quadtree
decomposition representation to remove the noise in images; Adler et al.
 proposed a discrete MRF approach, which employed the maximum a posteriori estimation on the quadtree
so as to reduce the computational expense.
Firstly, in view of the fact that the 3D scene is far greater than the radar beam and there generally exists plenty of objects which are definitely can not be detected by radar, this paper adopts quadtree
to establish and query the 3D scene.

This state aggregation method facilitates the planning and heuristic generalization of our EQ LRTS (encoded quadtree
algorithm seems to be the best one, having the best compression rate, the best memory usage and some good compression and decompression times.
