| Abstract: | The correlation identification system,based on volume holographic
associative storage and wavelet transform,has an inherent multichannel processing
characteristic.The geometrical parameters determining the parallelism of the volume
holographic wavelet correlation system are analyzed.The approaches to increase the number of
output correlation channels are offered.The parallelism of the system constructed in this paper
is estimated as an example.The recognition of 120 human faces is realized and experimental
results are given. |
