Advanced stitching parameters

[krupkat]

Bring in some of the options from stitching_detailed.

1. Identify which options would be useful
2. Implement

The goal is to keep the app simple to use and the defaults should "just work".

Calling the OpenCV function: Code location
Options menu: Code location

Implemented selectable panorama projection (definition, gui).

Candidate set functions from cv::Stitcher to call:

• setExposureCompensator
• setSeamFinder
• setCompositingResol

Masking would be an essential feature (like the include/exclude masks in Hugin). A few reasons:

• lenses are not perfect, they're usually sharp near center and soft near edges, or focus point shifted from shots to shots. Even if the software is smart enough to guess the best/sharpest sections, sometimes users would want to decide what's important.
• movement between shots: if half of a person is in one shot, that portion should be excluded, but sometimes users want to include certain person.
• best selection: group shot is a typical example, users might want to avoid the closed eyes in one shot and pick the smiling faces in another.

Or, better yet, Segment Anything: https://github.com/facebookresearch/segment-anything :-)

Thanks for an awesome modern approach.
