This paper presents a method for the automated anatomical labeling of bronchial branches extracted from 3D CT images based on machine learning and combination optimization. We also show applications of anatomical labeling on a bronchoscopy guidance system. This paper performs automated labeling by using machine learning and combination optimization. The(More)
Exhaustive enumeration of stereoisomers is one of the most fundamental and important problems in chemoinformatics. In this paper we deal with chemical compounds composed of carbon, hydrogen, oxygen and nitrogen atoms whose graphical structures are tree-like graphs, and consider stereoisomers caused only by asymmetry around carbon atoms. We introduce a(More)
Exhaustive and nonredundant generation of stereoisomers of a chemical compound with a specified constitution is an important tool for molecular structure elucidation and molecular design. It is known that many chemical compounds have outerplanar graph structures. In this paper we deal with chemical compounds composed of carbon, hydrogen, oxygen, and(More)
This paper presents a method for an automated anatomical labeling of bronchial branches (ALBB) for augmented display of its result for bronchoscopy assistance. A method for automated ALBB plays an important role for realizing an augmented display of anatomical names of bronchial branches. The ALBB problem can be considered as a problem that each bronchial(More)
BACKGROUND To identify the clinical T stage by endoscopy is a major diagnostic goal for superficial esophageal squamous cell carcinoma (ESCC). The completion of a microvascular morphological study of mucosal lesions is necessary to optimize therapy. MATERIALS AND METHODS Images of 197 intra-papillary capillary loops (IPCLs) captured by magnified endoscopy(More)
Datacenters are now widely used, and their sizes are increasing due to the rapid spread of cloud computing. Meanwhile, the cost of IT-system operations occupies 60% of the total cost in a datacenter. So far, improving operations has been focused on automating operations with operation management middleware. However, designing operational procedures,(More)
Humans shake hands as a sign of greeting when they first meet one another to express a feeling of rapport. A handshake is an embodied interaction that involves physical contact. For interactions involving a human and a robot, if the robot generates a handshake motion that is emotionally acceptable to humans, it will lessen any feeling of aversion that the(More)
Nonredundant and exhaustive generation of stereoisomers of a chemical compound with a specified constitution is one of the important tools for molecular structure elucidation and molecular design.
