abstract = "The arteriography exams are useful for checking abnormalities in
the blood vessels and diseases such as stroke, stenosis, bleeding
and especially in the diagnosis of Encephalic Death in comatose
individuals. Because it is a complementary test in the diagnosis
of brain death, the use of strategies that may help their accuracy
is of paramount importance and, therefore, were compared three
pre-processing techniques. The first technique uses only the
bilateral filter to minimize the noise present in the images, the
second one uses the transformed intensity by Sigmoid to enhance
the arteries before the count of the pixels, and finally, the
third technique uses the bilateral filter along with the
transformed intensity by Sigmoid. After processing, a comparison
with the results of the three techniques was performed in order to
obtain the best one to be used in further processing. For 14 tests
quantified, including Encephalic Death 7 and 7 Other Cases, the
technique achieved a most satisfactory number of pixels quantified
was the second technique, which uses a Sigmoid transformed
intensity.",
