Registration of Consecutive Frames From Wireless Capsule Endoscopy for 3D Motio...
Oliveira, Marina; Araújo, Helder; Figueiredo, Isabel N.; Pinto, Luís; Curto, Eva; Perdigoto, LuísWireless Capsule Endoscopy (WCE) is a non-invasive medical procedure devised for painless in vivo inspection of the gastrointestinal (GI) tract. It is especially valuable for the examination of the small intestine since it is dif cult to reach by traditional endoscopic procedures. The setup includes a camera with an embedded light source and a circuit capable of acquiring and transmitting the video. The main ch...
Wireless Capsule Endoscope Location and a Robotic Validation Experiment
Figueiredo, Isabel N.; Pinto, Luís; Perdigoto, Luís; Oliveira, Marina; Araújo, Hélder; Figueiredo, Pedro N.We present results concerning the validation of a novel approach for wireless capsule endoscope localization, using as ground truth a simulated biological/mechanical environment experiment. The approach relies essentially on image-based methods. It involves a hybrid multi-scale affine and elastic image registration procedure which is afterwards appropriately complemented with calibration and visual odometry tec...
