Influence of information content of partially occluded images on the results of recognition

摘要

The problem of detection by optical correlation of an apertured input scenes has been analyzed yb digital simulation and in an optical experiment. The chosen input scenes included various kinds of elements with different Fourier spectrum: high medium, or low frequency. Digital and optical recognition results (correlation peak value, PCE ratio, and peak location) are discussed as a function of various level of occlusion and various information conetent of the input sences.
