Improving Object Detection Accuracy with ESP32-CAM and OpenCV

The human eye and brain do lots of image processing “in the background” that is extremely difficult to imitate with cameras and computer algorithms. For example, mere color recognition under changing light conditions is a far more difficult problem than most people realize.

Also keep in mind that the eye has logarithmic response to illumination levels spanning many orders of magnitude, whereas cameras have linear response. As mentioned above, a better camera with greater bit depth will help overcome that range problem.
