stitch.py and pagegraph.py mixed laser odometry, image registration,
frame correction, canvas handling, pose-graph maths and the two stitchers.
They are now modules of myscan/stitching, which imports nothing from the
device code:
geometry rigid transforms, pose vectors, warp_add
filters grayscale, high-pass, feather weights
correct Corrector: undistortion + flat field (and weighted variant)
odometry LaserOdometry: the laser model and the phase-correlation
override, shared by both stitchers
register ECC, phase correlation, SIFT matching, overlap agreement
canvas growable Canvas, layout, parallel render, normalize/compose
posegraph robust Gauss-Newton, largest connected component
loops keyframes and loop-closure candidates
pagegraph PageGraph, now orchestration only
incremental Stitcher, on the shared Canvas
The stitchers take a Corrector and an odometry object (anything with
predict()) instead of building them, so another device can supply its
own motion prior. live.py drops its own canvas and normalisation for the
shared ones; PageGraph's mosaic check uses the parallel renderer.
Output on scan_text is unchanged (global stitcher identical, incremental
within 1 grey level). stitch.py --live now applies lens correction too
(--no-undistort restores the old output).
