• Added --comments option for ROI writer to insert comments at the beginning of written files.

• Input directories read all contained files ending in .report when using adams format.

• Added --sample-stride option to tfrecords input which sub-samples the mask when generating the polygon for speed increase.

• Added --mask-threshold option to tfrecords input which sets the probability to consider the mask inside the polygon.

• Internal format is now an object rather than a tuple.

0.2.0 (2020-03-06)

• Conversions now automatically discard annotations with zero area, can be reverted with --include-zero-area flag.

• Added the ability to specify a prefix and suffix for reading/writing ROI files.

• Moved utilities for each format into their own sub-package.

• Added reader options to read input files from list files.

0.1.1 (2020-01-23)
