Capsule endoscopy was introduced to gastroenterology with the aim of improvement of the diagnostics means for these parts of gastrointestinal tract which are difficult to reach with a classical endoscopy. Modern capsules are equipped with an on-board light source and a camera Acquired images are transmitted to a video recorder. The next generation capsule that is developed within the VECTOR (Versatile Endoscopic Capsule for gastrointestinal TumOr Recognition and therapy) project will also make it possible to transmit a video stream in real-time. The video recording generated by the endoscopic capsule during its passage through gastrointestinal tract is of a considerable length and the automatic detection of its specific regions would enhance diagnostic capacity of the procedure. Therefore, a special algorithm has been developed and implemented in C++. The algorithm is meant to be used for automatic region classification within video recordings (streams) that can be obtained with an endoscopic capsule.
