Parallel optical-feature extraction by use of rotationally multiplexed holograms.
We propose a novel rotational (peristrophic) multiplexing method of hologram recording for parallel opticalfeature extraction and report basic experimental results. The features to be extracted are line-segment orientations separated by 30 degrees . The extracted features can be used for f lexible pattern recognition.
