  • Wide field-of-view imaging system using a spatial light modulator
    Patent number: 6421185
    Abstract: A foveated imaging system using a relatively simple optical imaging system with a spatial light modulator located at or near a pupil plane to correct aberrations. Maximum resolution is obtained for a limited region defined by a single fixation point (a foveal region) within the field of view. The fixation point can be changed manually, by using a predetermined scan pattern, or automatically varied for surveillance or tracking applications.

  • Method and apparatus for pattern mapping system with self-reliability check
    Patent number: 5335291
    Abstract: A pattern mapping system provides indication of reliability of pattern or category selection indicated by output nodes. The indication of reliability includes a quantitative indication of error in the output and an indication when training is insufficient for the system to respond to the input pattern accurately. The error indication is based on error in the outputs produced by the system as trained in response to given inputs, and accuracy of fit of training data to the output. The insufficiency of the mapping system as trained is determined according to training data density local to the subject input pattern.
