What is in SeedCadence
Twelve parts. Each one says what the app does, what code checks and what you do.
Know at once when a photo is not good enough to count.
- SeedCadence AI: Reads the sharpness, light and shine of the photo
- Code checks: Fixed limits decide pass or try again
- You: Take the photo again if asked
Every seed on the tray is found and counted.
- SeedCadence AI: Finds each seed in the photo
- Code checks: Compares the number found with the number you placed
- You: Tap any seed it missed
Each seed is marked sprouted or not sprouted.
- SeedCadence AI: Looks for a small root on each seed and says how sure it is
- Code checks: Applies the "how sure" levels for the crop
- You: Fix any seed with one tap
When the app is not sure, it asks. It never guesses quietly.
- SeedCadence AI: Flags seeds it is not sure about
- Code checks: Also flags touching seeds and a root that seems to vanish
- You: Answer "Sprouted", "Not sprouted" or "Cannot tell"
parts in the app
Each part checks itself with code.
A seed keeps its number from the first photo to the last.
- SeedCadence AI: Matches each seed to its place in the first photo
- Code checks: A sprouted seed can never go back to not sprouted without asking you
- You: Confirm matches if the tray moved
See which seeds sprouted since the last photo.
- SeedCadence AI: Compares each seed with the photo before
- Code checks: Records the last photo with no root and the first with a root. Never a time in between
- You: Read the tray day by day
A printed card that lines up every photo of a tray.
- SeedCadence AI: Reads the four marks and flattens the photo
- Code checks: Checks the card belongs to the tray you chose
- You: Print one card for each tray
See how far a test of this size can be from the truth by chance.
- Code checks: Works out the range from the number of seeds
- You: Test more seeds for a narrower range
For a batch where 80 in every 100 would sprout, a test of 50 seeds shows 69 to 91 in every 100, 19 times in 20.
A tray that differs from the others is pointed out.
- Code checks: Flags a tray only when it differs more than chance allows
- You: Look at that tray again
A PDF and a CSV that never change after signing.
- Code checks: Locks the files and stores their fingerprints. A fix makes a new version
- You: Sign when the count is right
Every number leads back to its seeds, its photo and who decided.
- Code checks: Adds the seeds up again each time
- You: Open any number to see what is behind it
9 of 10 seeds sprouted. That is 90 out of every 100.
Behind it: seeds 1, 2, 3, 5, 6, 7, 8, 9, 10, on photo Hour 36.
A card to share after a Quick check.
- Code checks: Prints who tested and when, and that the card is for your own quality checks
- You: Share it or keep it
