Aim:

  • Learn how to classify annotations
    • Make annotations of tumor and stroma regions
    • Classify the annotations as stroma and tumor

2.6.1 Annotate the stroma and tumor regions¶

Create a new project and import the images of the dataset 02_HE_images. Open the image 101. Use the wand tool to annotate tumors and stroma.

2.6.2 Classify the annotations¶

Classify the annotations using the classes Tumor and Stroma.
