PrerequisitesBefore starting this lesson, you should be familiar with:
Learning ObjectivesAfter completing this lesson, learners should be able to:
Manually segment parts of a 2-D (3-D) image.
Manual segmentation is useful in many ways. If the dataset of interest is small, manual segmentation may be faster than designing an automated segmentation workflow, or automated segmentation may be very difficult. In addition, manual segmentation can serve as training and validation data for (deep-learning based) automated segmentation algorithms.
