%X Perspective shape from shading can be solved by combining static Hamilton-Jacobi(HJ) equation and fast sweeping method.To optimize the solution of static HJ equation and improve the results of perspective shape from shading,this paper uses high-order local Lax-Friedrichs(LLF) flux splitting scheme to increase the accuracy of partial derivatives.Besides,the paper uses modified weighted essentially non-oscillatory(WENO) scheme,which only uses integer grids and gets higher accuracy than WENO by using amended s...
