概要

Video capsule endoscopy (VCE) represents a significant advance in examinations of digestive diseases by providing a non-invasive method to view the small bowel. In addition, VCE provides a valuable source for visualizing the intestinal contractions, which are mainly events for intestinal motility assessment. However, the advantages of VCE diagnosis technique are facing with the time consuming for reading video sequence as well as challenging to detect the intestinal contractions. In this paper, we present our works to approach these motivations through techniques of VCE analysis. VCE interpretations could be implemented by analyzing spatial and temporal features. First, several image features such as color, edges, and motion displacement are extracted. Then their temporal analyses are presented in several ways to adapt with different tasks. Two applications utilizing this framework are developed. In the first …
