ABSTRACT:
A system for enhancing a binary data bit stream derived from a two-dimensional pattern image wherein, in a preferred embodiment, each data bit in the bit stream and a preselected group of bits associated therewith are sequentially stored in a first location and in associated preselected locations, respectively, of a storage circuit of a first enhancement stage. The bits associated with each data bit are utilized as an address to cause a read only memory to develop a decision bit as a function of the address. A gating circuit develops an output bit in response to each data bit and its associated decision bit. The sequence of output bits forms an enhanced data bit stream which appears at the output of the first enhancement stage for further application to one or more additional cascaded enhancement stages.
