ANNOTATION LINE DETERMINING UNIT, ANNOTATION LINE REMOVING UNIT, MEDICAL DISPLAY, AND METHOD THEREFOR

摘要

To detect annotation lines in medical image data. Horizontal annotation pixel determination means obtains the color component value difference between each pixel of a predetermined number of connected adjacent pixels in a first direction of the target pixel and an adjacent pixel thereof. If the total number of pixels having color component value differences, of the predetermined number of pixels is equal to or smaller than a first threshold, the horizontal annotation pixel determination means determines that the target pixel is an annotation pixel. If annotation pixels are successive in the horizontal direction in a predetermined number, horizontal annotation line determination means determines that the annotation pixels form an annotation line. The same applies to the vertical direction. The determined annotation lines are provided to border detection means.

主权项

1. A device for determining annotation lines added to regions in which medical images are displayed, comprising:
annotation pixel determination means configured to obtain color component value differences between each pixel of a predetermined number of connected adjacent pixels in a first direction of a target pixel and an adjacent pixel thereof and, to determine that the target pixel is an annotation pixel if a total number of pixels having color component value differences, of the predetermined number of pixels is a first threshold or less; and annotation line determination means configured to, if the annotation pixel is successive in the first direction in a number equal to or greater than a second threshold, determine that a line formed by the successive annotation pixels is an annotation line.
