Abstract
A computer image display system in which digital sampled data, generated by an image transducer and processed by a computer, is convolved with a Gaussian function in a display processor in order to produce a continuous analog image presentation on a diplay. First, the Gaussian function is convolved vertically with computer stored intensities in a vertical slice of interest, that is, multiplied by those intensity values in the vertical slice and summed to derive a resultant intermediate value on a given horizontal line. Then, the Gaussian function is convolved with the resultant intermediate value on a given horizontal line in order to derive final values which are to be displayed.
