Title:
REGION OF INTEREST LABELING DEVICE FOR BONE MARROW INTERPRETATION, AND REGION OF INTEREST DETECTION SYSTEM COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2020/141812
Kind Code:
A1
Abstract:
According to an embodiment of the present invention, a region of interest may be automatically labelled and detected for bone marrow interpretation. To this end, an embodiment of the present invention may comprise a region of interest labeling device for bone marrow interpretation, the region of interest labeling device comprising: an image scaling unit which downscales a stitching image obtained by stitching multiple divided images obtained through motion control imaging of a bone marrow specimen slide; a color conversion unit which converts the RGB color type of the scaled stitching image into an image-processing color space; a segmentation unit which segments, by applying multi-thresholding including high thresholding and low thresholding, the stitching image that has been converted into the image-processing color space; a morphology conversion unit which enhances a cell nucleus image by performing a morphology opening operation on the stitching image if the stitching image is segmented by applying the high thresholding, and enhances a cell continuity image by performing a morphology dilation operation on the stitching image if the stitching image is segmented by applying the low thresholding; a labeling unit which detects, on the basis of the enhanced cell nucleus image, multiple reliable cells to label the detected reliable cells, and detects, on the basis of the enhanced cell continuity image, particles or abnormal cells to label the detected particles or abnormal cells; and an occlusion cell filtering unit which removes, from the multiple labeled reliable cells, one or more occlusion cells occluded by the labeled particles or the labeled abnormal cells.
