    Topics for Exam 1:
    This sheet is intended to help you prepare for the first midterm in this course. The exam will cover all readings and lectures up through Friday, September 26, Seeing Depth. The exam will be closed book and closed note. The following list of topics should help you study for the exam.

    1. Properties of Light

      Light as photons and waves
      The frequency spectrum
      The eye as a pinhole camera
      Perspective projection
      Vision as an ill-posed problem
      Assumptions made by the visual system

    2. The Eye

      The lens and accommodation.
      The optic disk (What is it?)
      Filling in of blind spot.
      Photoreceptors: Rods and Cones
      The Fovea
      Retinal Ganglion Cells
      Center-surround receptive fields

    3. Central Visual Pathways

      Main pathway from retina to extrastriate cortex
      Basic structure of retina, LGN and striate cortex
      Optic nerve and optic chiasm
      Layered structure of LGN and cortex
      Two major processing streams (Dorsal and Ventral) and their functions

    4. LIghtness, Brightness and Edges

      Brightness vs. Luminance
      Dark adaptation
      Contrast effects
      Finding Edges
      Craik-Obrien-Cornsweet illusion
      Smoothing and Localization of edges
      Finding zero crossings
      Center-surround receptive fields and zero crossings.

    5. Seeing Motion

      Causes of Image motion
      Uses of image motion for determining scene properties
      Neural circuit for motion direction selectivity
      Motion processing in V1 and MT

      The aperture problem
      Motion adaptation
      Motion parallax
      Structure from Motion
      Biological motion
      Seeing where you're going

    6. Seeing Color

      Wavelength and color perception
      Hue, Saturation and Brightness
      Trichromatic color theory
      S, M and L type cone photoreceptors
      Color opponency/Color adaptation
      Color opponent receptive fields
      Color contrast
      Color constancy/ Retinex theory
      Color blindness

    7. Seeing Depth
