Figure 14From: Novel coarse-to-fine dual scale technique for tuberculosis cavity detection in chest radiographs Comparison of candidate detection in the coarse feature classification step using (a, d) GTM + LBP, (b, e) GTM + HOG, (c, f) GTM + LBP + HOG. Note that in the first row HOG misses the cavity but LBP is able to detect it. In the second row, LBP misses the small cavity but HOG can detect it. In both rows our technique is able to detect all the cavities.Back to article page
