Mask R-CNN
Mask R-CNN finds objects and colors the exact pixels that belong to each object.
What it does
Mask R-CNN finds objects and colors the exact pixels that belong to each object.
Segmentation: Outlining an object • Instance: A single specific object
How it works
- Find an object in the image.
- Draw a box around it.
- Make a mask that covers the object shape.
Uses & Applications
- A medical tool can outline a tumor area for a doctor to inspect.
- A photo editor can select one person from the background.
- A robot can understand the exact shape of an object it should pick up.
In short
It finds precise boundaries, such as a tumor in a brain scan.
Try it yourself
Color in each object
A box says where an object is. A colored mask tries to say exactly which tiny picture squares belong to it.
Your turn
Change one setting at a time. Reset example puts everything back.
