Optical Wavelet Preprocessing.
Abstract
A low resolution image was used for object recognition using an optical correlation technique. The low resolution image was an approximation of the original image that was derived using a discrete wavelet transform. The low resolution image was cross correlated with an image containing an object of interest. Using an inverse wavelet transform, the cross correlation result was synthesized to the resolution of the original image. This approach avoids cross correlating an image multiple times and passing information between levels of an image representation. It was shown that objects could be recognized that were approximated at 1/4 the original resolution using binary phase only correlation filters. Discrimination decreased at the lower resolutions, but the technique looks useful for object recognition.
