Then the FC-CRF enforces global consistency and provides fine. This section describes the trilinear interpolation algorithm using pseudo-Fortran code. Trilinear Interpolation Written by Paul Bourke July 1997 Trilinear interpolation is the name given to the process of linearly interpolating points within a box (3D) given values at the vertices of the box. The same results are obtained on the color image, as shown below, by applying the trilerp function on the color channels separately and creating separate image stacks for different color channels. Using the four nearest neighboring cells, bilinear interpolation assigns the output cell value by taking the weighted average. Likewise, a trilinear interpolant produces a characteristic cubic polynomial along the corresponding diagonal path where X==Y==Z. Coarse voxel predictions from a 3D Fully Convolutional NN are transferred back to the raw 3D points via trilinear interpolation. Artificial intelligence (AI) is about to transform medical imaging.
