Systems and methods for indexing and retrieving images are described
herein. The systems and methods analyze an image to determine its texture
moments. The pixels of the image are converted to gray scale. Textural
attributes of the pixels are determined. The textural attributes are
associated with the local texture of the pixels and are derived from
coefficients of Discrete Fourier Transform associated with the pixels.
Statistical values associated with the textural attributes of the pixels
are calculated. The texture moments of the image are determined from the
statistical value.
