CS564: Homework Assignment 4

Depth perception (Due November 30)

For this exercise you need to understand Depth Perception chapter in the NSL book.

As the homework you are going to study stereopsis in a three eyed system (better be called triopsis).

  1. Assume that three eyes are co-planar (in the same plane) as in the following configuration:

    2. In this system will there be an ambiguity as in stereopsis for two point targets? Justify your answer by drawing lines and relevant math/arguments.

    Write down your answers.
  2. This part is NSL coding and simulation.

Write DEV disparity module without any internal dynamics (no competition and cooperation dynamics within the module which means no differential equations using internal variables as inputs). Instead create 2 DEV (identical) module instances for L-R and R-S eye pairs with suitable interaction in between. The dynamics (the differential equations you wrote in simRun()) will be such that it will eliminate the false targets in both modules and lead convergence into the agreed real targets in both layers.

Submit the printout of your implementation and describe (on the printout next to simRun()) what you intend to achieve with the dynamics you coded.

Submit printouts showing the (at least 5) steps of your simulation to show that your model is doing what it is supposed to do (i.e. converge to real targets).

(Hint: for the interaction of two modules you may inspire from House model)
