How to use RedenFlow
One job, filmed from start to finish: an empty project, sixteen photographs of a fruit line, and a model that counts oranges as they go past. Every clip below is the real application on a MacBook Air.
Step 1
Make a project
Name it, say where it should live, and list the things you want to find. One class is enough to start with.
A new project, three short questions. Step 2
Bring the pictures in
Drag in a folder of photos, or hand it a video and say how many frames to take. Fewer frames means less to label; more means the model sees more of what can happen.
How many pictures you needThirty frames pulled out of a video, one in every eight. Step 3
Click on the thing you care about
This is the part that decides whether the job takes an afternoon or a week. Click an object and the outline is drawn for you. Press Enter to keep it. Most of the time you are agreeing with it rather than drawing.
One click per orange. The outline follows the fruit, not a box around it. Step 4
Make more of the pictures you have
Flips, rotations, crops, colour and blur, each one a copy of what you already labelled. Sixteen labelled photographs became a hundred and eighty one here.
Sixteen originals in, a hundred and eighty one out. Step 5
Press train and walk away
Pick a model size and a number of passes. One number tells you whether it is working, and the app says in words whether it is still moving or has settled. This run took fifty three minutes on a MacBook Air, using the Mac's own graphics.
Is your graphics card being usedFifty three minutes, sped up. The score drops early, which is normal, and the app says so at the time. Step 6
Say what it should do
Not just export a file: choose the job. Show a live window, count what goes past, write a spreadsheet, keep a recording. Then pick where it runs and what it watches, and it writes a folder you can hand to somebody else.
Putting it on a Jetson or a PiFour jobs to pick from, and you can pick more than one. Step 7
Draw the line it counts across
Drag a line over the picture, where the things go past. Anything that crosses it is counted once, however long it stays in view. Name the classes to count, or leave it empty and it counts everything.
The line goes where the fruit passes. Two handles, and a box for what to count. Step 8
And then it runs
That folder, pointed at a video file. It finds the fruit, follows each one, and counts them as they cross the line. Nothing here went to a server: the model is on the machine and so are the pictures.
The finished model counting oranges. The total climbs at the top right.
That is the whole thing
No notebook, no cloud upload, no configuration file. The free plan covers three projects and one training run, with no card and no time limit, so you can walk this whole path before deciding anything.
