Content-based Image Database Retrieval By Generalized Complex Moments

BRIEF DESCRIPTION

Generalized complex moments of a binary image are features invariant to affine transformations. We apply these features to determine the fold number and mirror symmetric properties of binary logos. Experiments show that these features are sufficient to index binary logos since nearly all logos are retrieved correctly by their affine-transformed versions. Currently, we are working indexing and retrieval of color images.
