Normalize keypoints locations based on image image_shape

Return depths of approximately uniformly spaced samples along rays.

Regularizer L_dev as in Equation 8

Computes the location of dual vertices as described in Section 4.2

Obtains the ID of topology cases based on cell corner occupancy. This function resolves the ambiguity in the Dual Marching Cubes (DM

Identifies grid cubes that intersect with the underlying surface by checking if the signs at all corners are not identical.

Identifies grid edges that intersect with the underlying surface by checking for opposite signs. As each edge can be shared by multi

Normalizes the given weights to be non-negative. If input weights are None, it creates and returns a set of weights of ones.

Tetrahedralizes the interior volume to produce a tetrahedral mesh, as described in Section 4.5.

Connects four neighboring dual vertices to form a quadrilateral. The quadrilaterals are then split into triangles based on the gamma

Generates a voxel grid based on the specified resolution. Args: res (int or list[int]): The resolution of the voxel grid

Compute the DICE loss, similar to generalized IOU for masks Args: inputs: A float tensor of arbitrary shape. The pred
