Currently, the issue of information search is based on processing a large number of documents, indexing their contents, and then evaluating the level of their adaptation to the question asked by the user. The development of the Web allows to offer certain on-line services which make it possible to shop, book tickets or deal with public-administration issues. The objective of the WKUP system (virtual...
The paper addresses data processing support that is required in capsule gastrointestinal endoscopy. First, capsule position estimation method using standard MPEG-7 image features (descriptors) is discussed. The proposed approach makes use of vector quantization, principal component analysis and neural networks. Next, new algorithms dedicated for virtual colonoscopy (VC) human body inspection are described...
The virtual colonoscopy (VC) techniques try to simulate a real colonoscopy. A doctor who makes real colonoscopy examination does not have optimal information about anatomical structures which he looks at. He sees the inner colon structure only. 3D visualization of the colon segmented from computed tomography (CT) data allows him to see the whole organ, its inner and outer part. The VC helps doctors...
The paper addresses the problem of very fast real-time estimation of forward and backward broncho-fiberoscope egomotion during the medical procedure of transbronchial biopsy. The proposed algorithm significantly differs from standard egomotion routines since it exploits specific rotational features of the bronchoscopic images resulting from the approximate cylinder-like structure of airway segments...
