Device, system and method for automatic detection of contractile activity in an image frame
First Claim
1. A method for identifying image frames depicting contractile activity of an intestinal lumen comprising:
- identifying a wrinkle pattern in an image frame, said wrinkle pattern including edges of a folded intestinal wall;
identifying a center of the intestinal lumen; and
determining whether the image frame depicts contractile activity.

Abstract
A device, system and method for automatic detection of contractile activity of a body lumen in an image frame is provided, wherein image frames during contractile activity are captured and/or image frames including contractile activity are automatically detected, such as through pattern recognition and/or feature extraction to trace image frames including contractions, e.g., with wrinkle patterns. A manual procedure of annotation of contractions, e.g. tonic contractions in capsule endoscopy, may consist of the visualization of the whole video by a specialist, and the labeling of the contraction frames. Embodiments of the present invention may be suitable for implementation in an in vivo imaging system.
