Nevertheless, one may see that the second step, that is, the
elimination of the white pixels due to the phase contrast
effects in the plastic region, is still more complex, and the
ANNs could not classify correctly a part of the plastic pixels
of the image. However, the results demonstrate the viability of
the use of ANNs for the segmentation of more complex X-ray
IlCT biomedical images. It is important to highlight that the
insect region was basically recognized.
In addition, the application of ANNs for the segmentation
of X-ray IlCT images may be extended to other modalities of
X-ray imaging.
