fast_paddle_ocr 0.0.5

High-performance real-time OCR plugin for Flutter using NCNN and PP-OCRv5. Supports live camera preview, flash control, and photo capture with integrated text recognition.

0.0.5

• Massive performance optimization: Decoupled camera rendering from OCR processing to guarantee smooth 60 FPS preview.
• Advanced Dual-Thread Architecture: Separated Detection (DBNet) and Recognition (CRNN) into dedicated background threads.
• Introduced IoU (Intersection over Union) Bounding Box Tracker for ultra-fast 15-20 FPS box responsiveness.
• Extreme battery & thermal efficiency: Throttled the heavy Recognition model to ~3 FPS while maintaining fluid UI.
• Smart Dynamic CPU Allocation: NCNN threads are automatically distributed based on device core count (30:70 ratio).
• Native C++ Text Filtering: Automatically cleans OCR output to strictly alphanumeric characters and dots.
• License updated to Creative Commons Legal Code.

0.0.4

• Added detect-only bounding box preview in photo mode (no OCR until capture).
• Full sensor frame capture: saved images now use the complete camera resolution.
• OCR processing limited to overlay/scan area only for accurate text detection.
• Bounding boxes and text labels drawn on full-frame output image.
• Added full-screen image viewer with pinch-to-zoom in example app.
