When a digital image of a uniform radiation source is obtained with a scintillation camera, the action of a variety of cortical receptive fields employed by the human observer can be simulated with a computer. A frequency diagram of receptor output can be generated by scanning the simulated receptor (which includes both exitory and inhibitory weightings of local image intensity). Although the measured frequency distributions exhibit a generally Gaussian shape, the dispersions are larger than… CONTINUE READING
