二维各向异性弹性波地震波传播模拟，采用FDTD(Finite Difference Time Domain)数值模拟方法及PML(Perfect Matched Layer))和Collino混合边界，吸收下过要优于单一吸收边界。

应用背景 It approximates or even outperforms previously proposed schemes with respect to repeatability, distinctiveness, and robustness, yet can be computed and compared much faster.关键技术This is achieved by relying on integral images for image convolutions; by building on the strengths of the leading existing detectors and descriptors (in casu, using a Hessian matrix-based measure for the detector, and a distribution-based descriptor); and by simplifying these methods to the essential.
