CHARACTERIZING A TEXTURE OF AN IMAGE
Among other things, a texture of an image is characterized by deriving lacunarity measures from the image based on a wavelet analysis.
1 . A machine-based method comprising:
deriving local densities of wavelet maxima based on a wavelet maxima representation for an image, the local densities being derived for multiple areas of image; and
using the local densities of the wavelet maxima in analyzing a texture of the image.
2 . A machine-based method comprising:
analyzing a probability distribution of a density of wavelet maxima based on a wavelet maxima representation of an image; and
using the probability distribution in analyzing a texture of the image.
3 . A machine-based method comprising:
deriving lacunarity measures based on an analysis of wavelet maxima in a wavelet maxima representation of an image; and
training a classifier based on the derived lacunarity measures, the classifier being trained for use in classifying images.
