about eq. (9)

[garrisonz]

Thanks your great work again!

In gaussian_model.py, fiter_3D = distance / focal_length * scale1 according paper eq. (9), new gaussian covariance matrix's scale should be $\sqrt{scale^2 + filter3D}$ But, why in function get_scaling_with_3D_filter() is $\sqrt{scale^2 + filter3D^2}$ ? Why square fiter_3D? Thanks

Hi, there is a typo in eq. 9, where v_k should be v_k ^2 in eq. 9. Will update it in the revised paper. Thanks for pointing it out.
