The three basic image-template operations, which are defined in Ritter's image algebra, can describe many image traforms. In this paper, three operations are implemented with three step of image operations including: weighting, shifting and superposition. A two-layer optoelectronic architecture is provided: in the multi-imaging-threshold layer, two kinds of weighting are done with an space linear intensity coding methods; in the correlating layer, the images are shifted and superposed. The correlated result is detected by a CCD, and further processed by an computer. Experiments on 1D images are demonstrated.
