| Problem | Likely Cause | Solution | |---------|--------------|----------| | Diacritics missing (e.g., "ung" instead of "ứng") | Wrong language model loaded | Ensure lang='vi' is set. Check PaddleOCR version > 2.5. | | Words broken into characters (c h à o) | Incorrect text detection | Increase det_db_box_thresh to 0.6. Merge adjacent boxes with custom logic. | | Confusion between "l" and "I" or "0" and "O" | Low resolution | Upscale image by 2x using cv2.resize(..., fx=2, fy=2, interpolation=cv2.INTER_CUBIC) . | | Poor performance on webcam | CPU bottleneck | Use use_gpu=True if available. Alternatively, reduce frame size to 640x480. | You can find detailed installation instructions on the
