EGGzaminer

Before you start, keep these ready:

• A smartphone or digital camera

• A flat white surface (white tray, chart paper, or white plate)

• Two rulers with clear millimetre markings (Faber-Castell
  or similar works best)

• Fresh eggs for testing

• A weighing scale (to weigh the egg in grams before cracking)

A clean setup helps the AI detect the egg white (albumen) more accurately.

Place a white sheet of chart paper or a white tray on a flat surface.

Keep both rulers ready beside the area where you will crack the egg.

Crack the egg gently onto the white surface. Try to keep the yolk intact (a slightly broken yolk still works, but results may be less accurate).

Tip: Photograph the egg within 15 minutes of cracking for the most accurate albumen spread measurement.

This photo helps measure the spread of the albumen and yolk circularity.

How to take it correctly:

Hold your phone directly above the egg and shoot straight down.

Use Portrait orientation (vertical).

Keep the phone 25–35 cm above the egg.

Make sure the entire egg + both rulers are visible in the frame.

Ensure the rulers run across the top and bottom of the image.

Use natural light. Avoid harsh shadows or direct flash.

✅ Good photo: Whole egg visible, rulers clearly readable, sharp focus, even lighting.

❌ Avoid: Angled shots, partial egg, blurry image, or harsh shadows.

Take the Side Profile Photo (Landscape Mode)

 

This photo is used to calculate Haugh Unit and egg height.

How to take it correctly:

Without moving the egg, lower yourself so your camera is at the same level as the egg.

Shoot in Landscape orientation (horizontal).

Keep the camera 15–25 cm from the egg.

Capture the dome shape of the yolk rising above the white.

Make sure at least one ruler is visible at the bottom or side of the frame.

Keep the camera level — do not tilt up or down.

✅ Good photo: Clear side view showing yolk height, ruler visible, level shot.

❌ Avoid: Shooting from above, egg cut off at edges, or tilted camera.

Open EGGzaminer in your browser.

Click Add Egg if you want to test multiple eggs.

Enter the egg name and weight in grams (weigh the egg before cracking).

Click the Top-Down slot and upload your top-down photo.

Click the Side Profile slot and upload your side photo.

After uploading, a Scale (px/mm) box appears below each image.

Click 🔍 Auto-detect. The app will try to read the ruler automatically.

If auto-detect works, you’ll see a confirmation message.

If it fails or shows a wrong value, measure manually: Count how many pixels equal 10mm on the ruler in the image, then divide. Enter that number.

You can also leave it blank — the app will estimate the scale automatically.

Better scale = more accurate Haugh Unit and yolk measurements.

Click the 🔬 Analyse Egg button.

The results will appear within a few seconds in the Results tab.

If the coloured overlay (blue = albumen, orange = yolk) doesn’t look accurate:

Click on the result row to expand it.

Click 🔭 Top-Down to view the overlay.

Adjust the Albumen Detection Sensitivity slider:

Move left if too much background is marked blue.

Move right if the albumen area looks too small.

Click Apply.

Note: Haugh Unit and Grade are calculated from the side profile and do not change with this slider.

Follow these tips to get the most accurate readings

• Photograph eggs within 15 minutes of cracking. Albumen spreads over time.

• Use natural or diffused room light. Avoid direct flash.

• Always keep the ruler visible in both photos.

• Weigh the egg before cracking and enter the exact weight.

• Crack eggs gently from a low height to avoid breaking the yolk.

• Let refrigerated eggs come to room temperature before testing.

• Use a clean white background for better AI detection.
