This package provides a generic implementation of the quadtree spatial partitioning algorithm. The aim of this package is to provide an out of the box working solution for simple 2D spatial ...

The approximation of planar wavefront in traditional Polar Format Algorithm(PFA) limits the effective scene size of PFA for high-resolution squinted Synthetic Aperture Radar (SAR). In this paper, a ...

A dark channel a prior defogging improvement algorithm combined with sky recognition is proposed to address the problems of failure of dark channel a prior for sky regions, artifacts and detail loss.
