* @brief compute spherical harmonics of an equirectangular projection image
|
||
|
|
*
|
||
|
|
* vtkSphericalHarmonics is a filter that computes spherical harmonics of an
|
||
|
|
* equirectangular projection image representing a 360 degree image.
|
||
|
|
* Its output is a vtkTable containing the third degree spherical harmonics coefficients.
|
||
|
|
* This filter expects the image data to be a RGB image.
|
||
|
|
* 8-bits images are expected to be sRGB encoded and other formats are expected to be in
|
||
|
|
* linear color space.
