THREE-DIMENSIONAL BIT MAP DATA OBTAINED BY CT APPARATUS, DENSITY ANALYSIS METHOD, RECORDING MEDIUM, AND PROGRAM

摘要

PPROBLEM TO BE SOLVED: To reduce an average difference between the brightness of a plurality of pixels before transformation and the brightness after the transformation to zero even if a change in brightness occurs in gradation transformation in the three-dimensional bit map data obtained by a CT apparatus. PSOLUTION: The quantity of gradations for digitizing the brightness is made odd in the three-dimensional bit map data obtained by imaging an article by the CT apparatus. PCOPYRIGHT: (C)2004,JPO
