ABSTRACT:
A method and apparatus for automatically identifying targets in sonar images utilizes three processing systems which preferably operate simultaneously. After the image has been filtered and Fourier transformed, a highlight-shadow detector classifies portions of the image as a highlight, a shadow or background according to greyness levels of pixels in such portions. A statistical cuer selects those portions which have been classified as a highlight or a shadow. A neural network then classifies the sets of highlight and shadow reports as targets or background.
