METHOD FOR VESSEL ENHANCEMENT USING DECIMATION-FREE DIRECTIONAL FILTER BANK

摘要

A blood vessel sharpness improving method using a decimation-free directional filter bank preventing a junction suppression and producing the successive blood vessel tri are provided to disassemble the blood vessel photographing image with direct images including the blood vessels having the similar direct. A blood vessel photographing image is disassembled to direct images by using a decimation-free directional filter bank. The disassembled brightness within direct images is removed. The sharpness from which the uneven brightness is removed of direct images is improved by using the filter. Direct images in which the sharpness is improved are reunited. The output image is generated.
