Abstract
An imaging system includes an image detector for producing a continuous image signal from an image received thereat; oscillation means coupled to the image detector for inducing a spatial oscillation in the image relative to the image detector; and a spatio-temporally matching filter in communication with the image detector and the oscillation means. The matching filter is configured to filter out aspects of the image signal not associated with the induced oscillation, to thereby provide enhanced image processing of the image.
Claims36
An image processor comprising:
- a primary detector array having a plurality of detector elements sensitive to an input image so as to produce an image signal;
- means for inducing a spatial oscillation in the input image relative to the primary detector array, whereby the image signal possesses a spatio-temporal motion signature of the induced oscillation;
- a secondary array of opponent center/surround detectors, each center/surround detector fed by one or more detectors from the primary detector array so as to extract improved contrast and motion information;
- means for calibrating each detector in the primary detector array with respect to neighboring one or more detectors in the primary and secondary detector arrays using the image signal during the oscillation;
- and
- a spatio-temporally matching filter, spatio-temporally matching the oscillation, in communication with the image detector and the oscillation means for providing enhanced image processing of the image, the matching filter being configured to filter out aspects of the image signal not associated with the induced oscillation, for filtering the image signal according to the spatio-temporal motion signature of the induced oscillation to retain those elements whose motions display modulation by the induced oscillation.

A method of image processing comprising the steps of:
- spatially oscillating an image in one or more dimensions relative to a primary detector array sensitive to an input image so as to produce an image signal possessing a spatio-temporal motion signature of the induced oscillation;
- feeding each of a secondary array of opponent center/surround detectors from one or more detectors from the primary detector array so as to extract improved contrast and motion information;
- calibrating each detector in the primary and secondary detector arrays with respect to neighboring one or more detectors in the primary and secondary detectors using the image signal during oscillation;
- and
- filtering the image signal according to the spatio-temporal motion signature of the induced oscillation to extract those elements whose motions reflect the induced oscillation.
