Automatic Labeling of Vertebral Levels Using a Robust Template-Based Approach

Figure 6

Example of peak detection (a). The blue line shows the intensity profile along the spine (after preprocessing). The red line shows the set of patterns. These patterns are based on the template and are adjusted at each new peak detection. A zoomed panel illustrates the process of peak detection (b). The last red peak on the right is being adjusted. The red horizontal arrow shows the range for which the correlation between the pattern and the profile is being computed.
