-The function LUT3D fills the output matrix with values from the look-up table. Indices of the entries
-are taken from the input matrix. Interpolation is applied for mapping 0-255 range values to 0-16 range of 3DLUT table.
-The function processes each element of src as follows:
-@code{.cpp}
-    dst[i][j][k] = lut3D[~src_r][~src_g][~src_b];
-@endcode
-where ~ means approximation.
-Output is a matrix of of @ref CV_8UC3.

-@param lut3D look-up table 17x17x17 3-channel elements.
-@param interpolation The depth of interpoolation to be used.
