The purpose of this study was to perform analysis of the films that show the major events of the Kennedy assassination in Dallas in November, 1963. The two films that were studied extensively were: the Hughes film, which shows windows of the Texas School Book Depository Building (TSBD) simultaneously with the Presidential limousine a few seconds prior to the first shot; and the Zapruder film, which shows the limousine and occupants during the sequence of shots. Many image analysis techniques were employed. These included: digital image processing (integration, inverse transform filtering, and binary quantization), stereo-photogrammetric profiling, mensuration, photointerpretation, and coherent optical filtering. Each area of study was selected based on its relevance to current questions and uncertainties of the assassination. Each question was addressed with the most appropriate analytic techniques, hence the variety of image analysis methods used. The primary areas of study were: the TSBD windows; a bullet trajectory study and its relation to a "single bullet theory"; Governor Connally's reaction; dynamics of the fatal head wound and reactions; and questions on the "Grassy Knoll". No evidence of conspiracy was found from the study. In fact, claims of conspiracy based on these events depicted in the films were found to be lacking in substance.
