Annotation Classes

Define multiple classes for different structures in your images. Each class has a unique color and label.

Classes represent different categories of structures you want to segment. For example:

• Class 1: Cell membrane

• Class 2: Nucleus

• Class 3: Background organelles

Managing Classes

• Add Class (+): Creates a new class with an auto-assigned color

• Select Class: Click a class to make it active for painting

• Toggle Visibility: Hide/show annotations of a specific class

• Delete Class: Remove a class and all its annotations

Class Colors

Each class is assigned a distinct color for visibility. Colors are chosen automatically to maximize contrast between classes.

Best Practices

• Create all needed classes before starting to annotate

• Use consistent class assignments across all slices

• The active class is highlighted in the class list
