ABSTRACT:
An image spectrum analyzer and method for cartographic feature extraction comprising an image, means for generating a Walsh function light pattern and for illuminating the image with the Walsh function light pattern to procuce a masked pattern, and means for receiving the masked pattern and for producing an electrical signal in accordance with same. A digital signal can be provided in accordance with the electrical signal, and a digital data processor under stored program control can provide a Walsh transform coefficient representative of the digital signal. More than one Walsh function light pattern can be generated by the apparatus and method of the present invention to produce more than one masked pattern, and representative Walsh coefficient. The Walsh coefficients can be used to perform cartographic feature extraction of the image.
