Images are 2D Arrays!
it's all numb3rs but you need to figure out the conventions...

How to segment the tumor?
Binary segmentation mask
Segmentation
means dividing up an image into different structures
foreground vs. background
Label Map
each identified structure has a unique ID
Datatype?
Comparison of Segmentation Techniques
Automatic Segmentation is a hard problem!
so much variability across subjects!
Semi-Automatic Segmentation
user places seeds
Manual Segmentation or Expert Segmentation is the "Groundtruth"
extremely time-consuming
2 Experts worked on this for 6 months
Atlas-based Segmentation
Registration / Alignment
Registration
mapping one subject to a standard space
mapping one image modality to a standard space
once in standard space, we can apply knowledge or compare
