    Topics for Final Exam:
    This sheet is intended to help you prepare for the final exam in this course. While you are expected to know the material presented prior to the second exam, this exam will focus on the material covered subsequent to the second exam, beginning with Lecture 20, Structure from Motion. The exam will be closed book and closed note, but you will be allowed to bring one 8.5 x 11 inch sheet of paper with your own notes on it (one side only) to use as a reference during the exam. The following list of topics should help you study for the exam.

    1. Structure from Motion

      The Kinetic Depth Effect
      The Rigidity Constraint
      The Incremental Rigidity scheme
      Psychophysics of Structure from motion
      Using velocity estimates to compute Structure from motion (Hildreth)

    2. Heading

      Motion Parallax
      Sources of information to compute heading
      Optic Flow Field
        For observer translation
        For observer rotation
        For combined observer translation and rotation
      Image velocities for a moving observer
      Experiment to test whether Eye movement information is used in computing heading
      Models for computing heading
        Error Minimization models
        Template models
        Motion parallax models
      Using Difference Vectors to compute heading (Longuet-Higgins and Prazdny)
      Model of Biological Heading Computation
        Center-Surround Motion Receptive fields
        Motion Subtraction stage (Receptive fields like MT cells)
        Template stage (Receptive fields like MST cells)
        Performance of model in the presence of rotations, moving objects and visual illusion
      Biological Motion Processing Pathway
      Properties of MSTd cells
        Responses to Radial, Planar and Circular patterns
        Responses to shifted centers of motion
        Integration of eye movement information

    3. Color

      Wavelength and Spectra
      Hue, Saturation and Brightness
      Color Space
      Trichromatic Color Theory
        Color matching
        Three types of color receptors (S,M and L cones)
        How additional receptors increase the number of colors perceived
        Detecting Intensity changes vs. Color changes
      Color Adaptation
      Color Opponent Cells (Single and Double opponent Cells)
      Color Contrast
      Color Constancy
      Retinex Theory
      Color Blindness

    4. Perceptual Organization

      Stages of Perceptual Organization
      Figure/Ground Organization
        Ambiguous Figures
        Principles
        Physiology
      Visual Interpolation
        Evidence for visual interpolation
        Occlusion and Completion
        Illusory Contours
