MakeACopy 2.5.0 (Release Candidate)
What’s new
- Replaced the previous corner-detection approach with a custom on-device ML model
(fully offline, no network access). - Improved document edge detection and perspective correction, especially for
distorted or angled pages. - Reduced external dependencies and improved long-term maintainability.
- Faster image capture: reduced focus timeout and paused live analysis during
capture for improved responsiveness.
Bug fixes
- Fixed connected components analysis for OCR preprocessing (was incorrectly
analyzing background instead of text). - Fixed memory leak in border noise clearing (SubMat resources now properly released).
- Fixed inconsistent angle validation in ONNX corner detection.
- Improved resource management for OpenCV contour processing.
Technical notes
- The new corner detection model is a lightweight ONNX model trained specifically
for document geometry. - Inference runs fully on-device via ONNX Runtime (NNAPI / XNNPACK).
- No cloud services, telemetry, or data upload involved.
