An example of CMBs detection. A Original SWS image. B Bounding box placement of CMBs predicted by the Mask R-CNN with a probability above 0.6. C Comparison between the CMBs region identified by the model and the groundtruth. The probability mask generated by the Mask-RCNN was binarized with a threshold of 0.6. The contours of binarized mask and ground truth were visualized in red and blue, respectively. CMBs cerebral microbleed; SWS susceptibility-weighted MR sequences
