    Abstract: This paper addresses range-spread target detection in compound Gaussion clutter modeled as spherically invariant random vector clutter (SIRV). A Strong scatterers integrator based on Anderson-Darling test (ADT-SSI) is addressed for the problem that MSDD has detection loss when falsely estimating the number of scatterers. For ADT-SSI, adaptively est... Show More

    Abstract: This paper addresses sparse range-spread target detection in non-Gaussian clutter model as spherically invariant random vector. An optimum scatterers integrator (OSI) is proposed for the problem that it is hard to accurately estimate the number of scatters of the spare range-spread target. The OSI is obtained by integrating the energy of strong sca... Show More

    Abstract: We present an effcient method for computing shadows of many light sources (e.g. 1,024). Our work is based on the observation that conventional shadow mapping becomes redundant as the number of lights increases. First, we sample the scene with a constant number of depth images (e.g. 10), which we call temporal shadow maps. Then the shadow map for ea... Show More
