A NEW RETINAL MODEL AND ITS APPLICATION TO THE COMPUTER ANALYSIS OF AERIAL PHOTOGRAPHSSadowski, Alexander M. 10 1900 (has links)
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.
