    摘要: A SLAVE coprocessor connectable to a MASTER processor and cooperating with at least one external memory. The coprocessor presents an internal memory communicating with an internal data line extending between a first and second interface circuit communicating respectively with the processor and the external memory; the internal memory contains a character composed of a rectangular matrix of pixels corresponding to a digitized alphanumeric character; and the coprocessor presents an electronic arithmetic unit for comparing a character from the internal memory with a reference matrix from the external memory.

    摘要: A system for comparing digital images, whereby a first and second data processing block receive respective data streams corresponding to a reference image and a detected image for comparison with the reference image. The data processing blocks detect reference points in the images, and generate data, which is supplied to a block for determining a first approximation of the function A.sub.o relating the two images. The system also presents blocks for successively refining the function relating the reference image to the detected image. (FIG. 1)
