I can think of two possible ways how to implement it. The simple one is
to do conversion from Luv color space to RGB in the decoder itself. This
should be pretty simple and straightforward, but it's not very clean way
since Luv has wider gamut than RGB.

In theory it would be better to make Hugin independent on input color
space. Implementing this would be probably very difficult and it would
involve huge code changes because of the following problems:

1. the loaded data are in Luv color space, but Hugin assumes input is in RGB color space. This would require explicit conversion of the image data. The algorithms would probably works as they are now even with Luv, but the conversion would be necessary for the preview a control points panel. BUT
2. there is no possibility to get the information about the colorspace from vigra::ImageImportInfo so currently there is now simple way how to do the conversion correctly.

Title:
  LogLuv TIFF is not supported

Status in Hugin - Panorama Tools GUI:
  New

Bug description:
  Add support for LogLuv TIFF. Image loaded is not visible in the the
  fast preview and has strange colors in traditional (slow) preview. The
  output of nona seems to be emty.

  For some example LogLuv TIFFs take a look at
