v0.0.7

Fixed:

• recognize: regression from changed network initialization
• recognize: also load uncompressed models (Python 3 port)
• re/segment: avoid creating invalid polygon coordinates
• ocrolib scale estimation: make DPI-dependent, add fallback for empty/noise pages
• ocrolib morphology: avoid rounding artifacts and asymmetry

Changed:

• ocrolib / all ocropy processors: boost performance via OpenCV/PIL intead of SciPy
• binarize: expose threshold parameter
• re/segment: require images to be binarized already instead of ad-hoc binarization
• re/segment: much faster line segmentation, better separation of neighbouring lines
• segment: much more robust fg h/v-line and bg column detection, new image detection
• segment: add AlternativeImage with h/v-line or image non-text clipped to background
• segment: rewrite of region aggregation via hybrid recursive X-Y cut
• segment: also annotate detected lines (at detected regions) after page segmentation
• segment: expose many new parameters
• segment: add all new lines/regions in proper (but only top-down left-right) reading order
• segment: add table level (like page segmentation, but horizontal-first split strategy)
• segment: also recurse into table cells for region level
• segment: incremental annotation (ignore and re-order existing text/image/separator regions)
• profile: remove this CLI, but keep integrated via API in new pure OCR-D CLI postcorrect
• wer, training: remove these CLI
• postcorrect, align: update to latest JAR
• remove non-OCR-D scripts from installation
• add uninstall target
• update documentation (esp. training, testing and postcorrection)
• improve/extend automatic tests
