Paper Abstract

This paper describes the philosophy and implementation of a two-dimensional transversal (finite impulse response) filter. The filter will provide automatic background cancellation and image enhancement in real time at rates in excess of 4 megapixels per second. The paper begins by discussing the philosophy of the filtering process as applied to typical electro-optic imagery together with computer simulated images illustrating its performance. A hardware architecture is described that causes a 15- x 15-pixel scanning window to pass over the image, performing a two dimensional convolution in real time with a weighting function that is programmable under the control of a microprocessor based console. To simplify the hardware design, certain restrictions are imposed on the kernel weighting functionnamely that it must constitute a rectangularly symmetric function.
