Bioimage processing device, bioimage processing method and bioimage processing program

摘要

A biological image processing device includes: a line extracting unit configured to extract at least one line from contours of a palm and principal lines of the palm shown in an image of the palm; a pixel extracting unit configured to extract pixels of the line extracted by the line extracting unit; a local region setting unit configured to set a local region for each of the pixels, each local region including each corresponding one of the pixels; a local orientation calculating unit configured to calculate, for each local region, local orientations of the line extracted by the line extracting unit, in accordance with gradient intensities related to respective orientations of each corresponding local region; and an orientation calculating unit configured to calculate an orientation of the palm in accordance with a statistical amount of the respective local orientations.
