Image object detection: This goes one step beyond classification to find the position (using bounding boxes) of individual objects. That's it! Mark image regions in non-destructive overlays (without changing pixel values). Synthetic data can also simulate edge cases and conditions that arent represented in real data or mitigate issues caused by potential changes in the camera sensor or lighting conditions, helping teams fill in the gaps in their dataset. You signed in with another tab or window. Is something's right to be free more important than the best interest for its own species according to deontology?
