Release Notes for Loghi-HTR Version 1.3.12

Date: 2024-03-22

Overview

Version 1.3.12 of Loghi-HTR introduces several enhancements and bug fixes to improve data loading, augmentation, model handling, and confidence score calculations.

Enhancements

• DataLoader Improvements:

  • The DataLoader now skips lines that are empty after stripping, ensuring cleaner data processing.

• Random JPEG Augmentation Adjustments:

  • The --random_jpeg augmentation has been adjusted to be less extreme, providing more realistic augmentations.

• Existing Model Channel Resetting:

  • When using the --existing_model option, the channels are now always reset to ensure consistent model behavior.

Bug Fixes

• Confidence Score Clamping:

  • Fixed a bug where confidence scores could exceed 1 due to precision errors. All confidence scores are now clamped to the range [0, 1]. A warning is logged whenever this clamping occurs.

• SavedModel Format Conversion:

  • The SavedModel format is now converted and saved to the new .keras format in the output/model.name directory. Starting from May 2024, the legacy format will only be usable for inference.

Contributors

• @rvankoert: Responsible for the DataLoader improvements, random JPEG augmentation adjustments, and existing model channel resetting.
• @TimKoornstra: Responsible for the confidence score clamping and SavedModel format conversion.
