Fix OpenCV Stitching Seams

I have an existing OpenCV pipeline that stitches two wide-angle camera feeds (code already written). It mostly works, but there’s a clear seam in the centre, plus some alignment and exposure issues (see example).

I’m not looking for a rebuild — I need someone to fix and improve the current code.

Tasks:

Remove visible seam
Improve alignment stability
Reduce exposure differences

Deliverables:

Updated working code
Short explanation of changes

This is the first task, with more work to follow (object detection/tracking).
