What it does

Faster R-CNN first finds places where objects might be, then checks those places carefully.

Region: A specific area of a photo • Proposal: An AI's guess

How it works

  • Scan the image for possible object areas.
  • Zoom in on each possible area.
  • Decide what object is inside each area.

Uses & Applications

  • A hospital tool can help point doctors to areas on medical scans.
  • A warehouse camera can count boxes on shelves.
  • A wildlife camera can find animals in photos.
In short

It is slower than YOLO but can be more careful.

Try it yourself

Find a shape, then name it

Your turn

Change one setting at a time. Reset example puts everything back.

Inspect regions before classification
