An Investigation into the Role of Cortical Computing Unit in Human Visual Pattern Recognition

摘要

It has been postulated that the neurons in the cerebral cortex are arranged so that the cortex is functionally a sheet of individual computing units coupled together horizontally and processing information perpendicularly through the sheet in a process described mathematically as correlation. A digital computer model is developed which simulates the proposed correlation function performed by the human visual system and is evaluated on the IBM 1620 and IBM 7094 digital computers. The computer model performs:(1) storage of a number of patterns; (2) correlation between input and stored patterns; (3) pattern translation correction; (4) pattern recognition; (5) pattern similarity recognition and short term memory simulation; (6) memory allocation. Recommendations are made for Fourier transform analysis, pivoted pattern analysis, and magnification effect correction. (Author)
