Abstract : This thesis analyzes the use of a discrete Fourier transform, a template and a frequency filter as scene analysis tools. That analysis leads to a problem formulation that permits mathematical optimization of the frequency filter. The problem is then recast to include the optimization of the transform and template as well. To permit straight forward synthesis, an alternate quadratic cost function is developed, and the minimization of that cost is reduced to a set of linear equations. (Author)
