Hugin Crop tab
Use the Crop tab to indicate the areas of the input images that hugin should be excluded from the stitching output. Note that unlike PTGui, setting crop parameters in hugin doesn't change the Field of View or optical centre of your images, it simply indicates areas of the image to be masked out.
(In detail, hugin uses the S 'selection' parameter in the i and o script lines instead of the C 'crop' parameter)
There are three situations where you might want to use crop parameters in hugin:
- With a scanned input image, there are usually black edges or marks along the sides of the image.
- With a circular Fisheye Projection image there are black unexposed areas around the image circle.
- Some lenses have a lot of flaring around the edges which you don't want to keep.
