• fixed "inverse" or "negative" image: YAML is updated with "negative" and Main Parameters GUI updates YAML and back

This represents a significant shift in PyPTV, from legacy parameters in .par files in parameter folders to YAML parameter files that contain all parameters, including plugins, a new option for the splitter (four-view splitter used with a single camera 3D-PTV), and numerous tests.

• two dependbot fixes
• fixed calibration GUI bugs

• added mask drawing not yet functional
• fixed many bytest to strings and back versus the new liboptv library == 0.3.0
• set continuous test using Docker
• tested newer numpy and Cython 3
• works with plugins like rembg (has to be installed separately)

• fixed the "previously fixed bug"

fixed the critical bug that was introduced in 0.3.2

• see latest commits from /blobs branch
• we fixed some naming issues for blobs and other cases.

• Fixed bug with optv.epipolar
• this release includes previous plugins
• and rembg plugin

• read_targets, write_targets is now in ptv.py
• we can read complex image file names but we write always simple target files f'cam_{id:d}.{frame:d}'
• bump_version can be used to update versions, use 'major', 'minor','patch'
• last patch is 0.3.0
• in parallel we updated test_cavity so take a look there

1. names in sequence are now with %05d instead of #
2. new background mask subtraction, works great with median image background in case of constant reflections.
3. new view of Detected Particles and Show Trajectories
