PT Unknown AU Jorge Bernal F. Javier Sanchez Fernando Vilariño TI Impact of Image Preprocessing Methods on Polyp Localization in Colonoscopy Frames BT 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society PY 2013 BP 7350 EP 7354 DI 10.1109/EMBC.2013.6611256 AB In this paper we present our image preprocessing methods as a key part of our automatic polyp localization scheme. These methods are used to assess the impact of different endoluminal scene elements when characterizing polyps. More precisely we tackle the influence of specular highlights, blood vessels and black mask surrounding the scene. Experimental results prove that the appropriate handling of these elements leads to a great improvement in polyp localization results. ER
