Table 2 summarizes all the revised methods for
identifying fractured bones.
4 CONCLUSIONS AND FUTURE WORK
The previous revision allows us to made a classifica-
tion of the methods used to identify both healthy and
fractured bone (figure 3). In order to identify fractured
bones, it is necessary not only to segment, but also to
label the bone fragments. Considering the previous
revision, threshold-based methods are used in most
cases. Currently proposed threshold-based meth-
ods obtain good results, but they can be improved
in some aspects. Due to the fracture, two different
fragments can be completely joined. This is specially
common in commin ...
