SYSTEM AND METHOD FOR ROTATION INVARIANT REPRESENTATION OF TEXTURE IN IMAGES

摘要

THERE IS DISCLOSED AN IMAGE PROCESSING DEVICE (110) CAPABLE OF RECEIVING AN IMAGE (200) HAVING ASSOCIATED THEREWITH A FIRST TEXTURE REPRESENTATION SPECIFIED IN A ROTATION VARIANT FORMAT ASSOCIATED WITH A CENTRAL REFERENCE POINT AND CONVERTING SAID FIRST TEXTURE REPRESENTATION TO A SECOND TEXTURE REPRESENTATION SPECIFIED IN A ROTATION INVARIANT FORMAT, SAID IMAGE PROCESSING DEVICE (110) COMPRISING: AN IMAGE PROCESSOR (120) CAPABLE OF ANALYZING ROTATION VARIANT TEXTURE PARAMETERS ASSOCIATED WITH SAID FIRST TEXTURE REPRESENTATION AND DETERMINING THEREFROM; A PLURALITY OF ROTATION INVARIANT TEXTURE PARAMETERS (351,352) DISPOSED ALONG AT LEAST ONE RADIAL LINE (360, 370, 380) EXTENDING THROUGH SAID CENTRAL REFERENCE POINT, WHEREIN SAID PLURALITY OF ROTATION INVARIANT TEXTURE PARAMETERS (351, 352) COMPRISE SAID TEXTURE REPRESENTATION; AND WHEREIN A NUMBER OF SAID PLURALITY OF ROTATION INVARIANT TEXTURE PARAMETERS (351, 352) IS EQUAL TO A NUMBER OF SAID AT LEAST ONE RADIAL LINE (360, 370, 380).(FIG 3B)
