For best results, use an image with good contrast between the wood and background.
Include a ruler or known reference object for calibration.

How to Use

  1. Upload an image containing the wood piece and a reference object (like a ruler)
  2. Calibrate by drawing a line along a known length and entering the actual measurement
  3. Select the area containing the wood piece by drawing a box around it
  4. Adjust threshold to isolate the wood from the background (darker pixels = object by default)
  5. Calculate to get the area in square centimeters
