Figure 13From: Novel coarse-to-fine dual scale technique for tuberculosis cavity detection in chest radiographs Comparison of candidates detection between HKG [[7]] and the proposed technique; (a, c) the results of HKG, ( b, d ) generated from the proposed technique. Green regions in the images are cavity candidates regions reported by the classifier, and blue dotted contours are the true cavities annotated by radiologists.Back to article page
