An apparatus for detecting the presence of a target in an n-dimensional array of digital data samples comprises: 1) a reading module, which reads the samples from the data array in overlapping groups; 2) a quantizing module, coupled to the reading module, which quantizes each of the overlapping groups of data samples and which generates an index that identifies the quantized group; and 3) a comparing module, coupled to the quantizing module, which compares indexes from the quantizing module to multiple reference indexes, each of which represents a quantized group of data samples that identify a distinctive feature of the target.
