| Abstract: | A real-time image intensifier using temporal filtering technique with pixel increment is described. An image seriously degraded by Gaussian noise becomes hazy no matter what image intensifying approach is used except the method of averaging which, however, is difficult to realize.From the definition of multiframe averaging, a mathematical model for pixel increment is derived. A practical circuit is designed and the circuit principle is discussed. It is found that the image S/N increases greatly with the circuit developed and the image quality considerably improved. The expensive and difficult high speed A/D converter is not needed in the image processing system. |
