A digital image texture analyzing method uses (302) the mean (µ 0 ) and variance (Ã 0 ) of the pixel values of an original image. Further, m × n filtered images are obtained (304) by filtering the original image using predetermined filters, each having a unique combination of one of m scales and one of n orientations, where m and n are predetermined positive integers, and the means ( µ 11 , µ 21 , ... , µ mn ) and variances (Ã 11 ,Ã 21 ,..., Ã mn ) of the respective filtered images are calculated (306). The texture analyzing method allows image textures to be more accurately analyzed and compared for similarity, even when an image is rotated and/or enlarged or reduced relative to another image. |
