Creating high-quality training data requires clean and well-thought labels.
AnnoStation supports the following two types of labels:
Type
Description
Segmentation
Segmentation is typically used to train the model to recognize the precise shape of an object. It is used to label each pixel of an image with a corresponding class of what is being represented.
Vector
Vector is often used to detect a certain object within an image. It is used to label the outline of shapes of an object with a corresponding class of what is being represented.
AnnoStation supports the following types of vector objects:
Point
Bounding Box
Polygon
Path
For vector labels, you can also define for additional classification.
Go to the Annotation Labels tab.
Click on Add label.
Provide a name and choose a color.
Select if the label is Segmentation or Vector.
For vector labels, you can define custom attributes.
Select Create Label.
When you want to classify an annotated object, using custom attributes is a powerful way.
