An Analysis of Oscillator-Based Computations for Image Processing.
Master's Thesis, University of Pittsburgh.

Abstract
Although there has been a vast amount of research into improving CMOS technology and computer architecture to make more powerful and efficient systems, the trends of decreasing sizes and energy and increasing power and speed are plateauing. Major roadblocks hindering the progression of Boolean logic based computing are transistor size, heat dissipation, clock speed, and computation power. This has inspired investigation into new methods for performing, complex operations not based on logic gates, or non-Boolean computations.
One such method is coupled oscillator arrays. Instead of a logic gates to compute
complex functions, the intrinsic physical properties of the oscillators can be used for computation making them more efficient for non-Boolean computations. This thesis will explore the use of coupled oscillator arrays to perform convolution, a primitive operation that plays a central role in many signal and image processing algorithms. Real-world circuit model parameters will be discussed and their impact on the circuit will be analyzed. In addition, this thesis will show the use of oscillators in Degree of Match (template matching), discrete cosine transform, discrete Fourier transform, Gabor filtering, and image compression. The effects of the model parameters on the will be examined on these implementations.
