Architecture of the Vision System
- We started with an architecture that largely adhered to biological
vision.
- The retina was a set of receptive fields (next slide).
- Primary Visual Cortex (V1)was a set of simple detectors including
line, edge, and vertex detectors.
- Each of these was location specific, and looked for single
pixel lines.
- Secondary Visual Cortex (V2) was used to recognized triangles.
- It took inputs from the line and vertex detectors, and
the large receptive fields in the retina.
- V2 had both position dependent and position independent
detectors.
- Position independent detectors were activated by
position dependent detectors
- This took advantage of the Cell Assembly work we've
been working on for years.
