Image analysis using enhanced spatial correlation functions.
By enhancing the high frequencies of the irradiance spectrum of a scene, it is possible to reconstruct an enhanced self-correlation function that clearly delineates its nondifferentiable regions. The technique has application in image analysis and pattern recognition. By way of example, the enhanced self-correlation function of a certain random process is furnished. Easily discernible are certain periodicities not apparent in the sample functions of the original process.
