Code optimization of speckle reduction algorithms for image processing of rocket motor holograms

Abstract

This thesis supplements and updates previous research completed in the digital analysis of rocket motor combustion chamber holographic images. In particular this thesis deals with the software code optimization of existing automatic data retrieval algorithms that are used to extract useful particle information from the holograms using a microcomputer-based imaging system. Two forms of optimization were accomplished, the application of an optimizing FORTRAN compiler to the existing FORTRAN programs and the complete rewrite of the programs in the C language using an optimizing compiler. The overall results achieved were a reduction in executable program size and a significant decrease in program execution speed.
