Title:
IMAGE PROCESSING DEVICE, IMAGE PROCESSING PROGRAM, AND IMAGE PROCESSING METHOD
Document Type and Number:
Japanese Patent JP2022128882
Kind Code:
A
Abstract:
To correct contour lines of blood vessels extracted from captured images.SOLUTION: An image processing device 1 corrects contour lines of blood vessels generated on the basis of captured images in which the blood vessels are captured. The contour lines include a first contour line and a second contour line. The image processing device comprises: a storage unit 12 which stores the captured image in association with position information of contour pixels corresponding to the contour lines of the blood vessels; a contour line selection unit 131 which selects one of the first contour line and the second contour line as a target contour line of correction; an extraction unit 132 which extracts the plurality of contour pixels as extraction pixels on the basis of the position information of the contour pixels; a pixel selection unit 133 which selects two extraction pixels having a prescribed positional relation as selection pixels; a correction pixel determination unit 134 which determines correction pixels corresponding to the target contour line after the correction on the basis of pixel information on a plurality of reference pixels arranged at prescribed positions from the two selection pixels; and a correction contour line identifying unit 136 which identifies the target contour line after the correction on the basis of the position information of the correction pixels.SELECTED DRAWING: Figure 2
