Reverts #3379 due to errors loading jpgs in Kaggle.

πŸ› οΈ PR Summary

Made with ❀️ by Ultralytics Actions

🌟 Summary

Refinement in image reading for consistent color channel handling.

πŸ“Š Key Changes

  • Removed the -1 flag from cv2.imread() in the utils/datasets.py.

🎯 Purpose & Impact

  • Ensures images are read in a consistent BGR (Blue-Green-Red) format by OpenCV, avoiding potential issues with color channels.
  • πŸ› οΈ Provides better stability in image preprocessing, which can lead to improved model performance and reliability.
  • Users can expect more predictable behavior when using custom datasets with varying image formats.
