title: Binary encoding of gray-scale nonlinearly transformed filters for optical pattern recognition.
abstract: A binary-encoded nonlinear matched filter for optical correlation is described. The gray-scale matchedfilter function, transformed by a general type of nonlinearity, is represented in a binary format by a threshold function that changes as a function of the spatial frequency. The output correlation term of the binary-encoded filter is equivalent to the output correlation term of the gray-scale nonlinear matched filter.
