QC 351 A7 no. 70 / In order to find a new and more economical method for the computer detection of object outlines in aerial photographs, the human visual system is considered. This leads to the concept of the human retina as a matrix of light receptors and permits the development of a three-stage retinal process. The first stage consists of the registering of the intensity distribution of the image. The second and third stages consist of operations that are analogous to the mathematical calculations of the first and second derivatives. This process is applied to the retinal matrix in a line-by-line method in two orthogonal directions. This retinal model is tested experimentally and applied successfully to two photo- graphs. The computer program that generates and performs the retinal three-stage process does so with a minimum of computer decisions, resulting in a highly efficient use of computer time. The successful application of this retinal model and its inherent economy of operation demonstrate its potential usefulness in the computer analysis of aerial photographs.

This thesis explores the function, classification, and re-contextualization of historical photographs as they are understood and digested by art museums. The Abel Boulineau French Regional Life collection at the Art Gallery of Ontario (AGO), which I researched, re-organized, and re-attributed during the summer of 2010, provides a case study for this topic. I investigate the contingencies of meaning surrounding late-nineteenth and early-twentieth century photography, and the inadequacy of art historical models for interpreting works not originally created as aesthetic objects. I explore how museums must understand and grapple with its early photography, and the implications of re-contextualizing such collections within its institutional discourses. The work of producing an attribution places necessary emphasis on photographs as historical entities, and recovers information about their original creation and circulation. Surveying the French Regional Life collection reveals both the pragmatic and theoretical issues involved in making an analysis of early photography.
