Module 01 Summary

What this module established

An image is a (height, width, channels) array of numbers, and nothing in it knows what it depicts. Rows come before columns in numpy while almost every drawing API takes x before y - which is where most transposed-image bugs begin.

Carry forward

• OpenCV is BGR and nearly everything else is RGB. Mixing them changes the colours and raises nothing.
• Permission is a property of the dataset and travels with every model trained on it. A weights file carries no provenance.
• Strip EXIF at ingestion. Faces, plates and screens need a decision before collection - content in a training set cannot be removed from a trained model.

Before moving on

Move on when your dataset card exists with prohibitions and gaps, and you can state the channel order your loader produces.
