4What are the three levels of Marr’s Computational Theory?

- Primal sketch (edges, lines, blobs), 2.5D sketch (viewer-centered depth and orientation), and 3D sketch (object-centered detailed representation).
- Recency (recent firing leads to higher activation) and Frequency (frequent firing leads to higher activation).
- Geometric ions, or basic shapes, that form the building blocks of object recognition.
