<title>Hybrid image processing</title>

Abstract

A combination of digital and optical image processing techniques makes the best use of each processing domain. Fourier optics offers speed, digital processing offers algorithmic complexity. One connection between the domains is digital image operations that produce shift invariance to image changes of a priori known character. Our video rate image coordinate transformation is an enabling technology for real time hybrid image pattern recognition. We outline some of the techniques and devices that are unique to the Johnson Space Center program
