Determination of structure component in image texture using wavelet analysis

This paper presents a wavelet-based method for determining a structural primitive in an image with regular texture. The overcomplete wavelet transform and autocorrelation function of its scaling image are used. An efficient peak-finding method is developed to detect peaks in the autocorrelation function for constructing two displacement vectors from which a parallelogram is formed as the structural primitive of the regular texture. Placement of the primitive in the image gives the structural component of the textured image
