Matched filtering of continuous tone transparencies using phase media

Contour and orthophoto mapping by optical matched filter correlation of complex exponentiated stereotransparencies

“…log technique is open-loop as is the correlator itself, and thus offers unique advantages and time savings. In May 1975, promising experimental results of an auto-correlation of phased inputs were reported (56). The cross-correlation of complex exponen tiated inputs will be analyzed in the subsequent chapters.…”

Pixel displacement determination in cascaded images utilizing coherent light fringe patterns

“…The two major types of techniques used in this area are image-image correlation (7,8,9) and image-matched filter correlation (10,11,12,13,14). Gopfert (10) gives an extensive list of references in this area up to 1976.…”

Pixel displacement determination in cascaded images utilizing coherent light fringe patterns

“…Since the development of the laser in 1960, both holography and coherent optical data processing have been used to determine parallax. The two major types of techniques used in this area are image-image correlation (7,8,9) and image-matched filter correlation (10,11,12,13,14). Gopfert (10) gives an extensive list of references in this area up to 1976.…”
