<p><P>PROBLEM TO BE SOLVED: To provide an image processing device, an image processing method and a program, wherein the noise of a curved striped pattern is properly removed from an image of the curved striped pattern and wherein ridge lines of a fingerprint or a palm print to which attention is paid are enhanced. <P>SOLUTION: The image processor includes: a data storage unit storing image data of a grayscale image including the fingerprint or the palm print and a ridge pattern direction distribution data indicating a direction distribution of a ridge patterns of the fingerprint or the palm print; a direction utilization image enhancement unit executing ridge line direction utilization image enhancement processing based on the ridge pattern direction distribution data to the grayscale image; and a direction extraction unit extracting a first direction distribution of a first pattern included in the image after the ridge direction utilization image enhancement processing from the image after the ridge direction utilization image enhancement processing of a result obtained by executing the ridge direction utilization image enhancement processing to the grayscale image. The direction utilization image enhancement unit executes first direction utilization image enhancement processing based on first direction distribution data indicating the first direction distribution to the grayscale image. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
