The gap has at least one opening through which in-vivo fluids may enter and/or exit the gap. The device further comprises an illumination source for illuminating the in-vivo fluids in the gap, a light detector for detecting light which passes through the in-vivo fluids in the gap, and flexible fins disposed on the housing in the vicinity of the gap's opening for covering the opening when the fins are folded and for pumping fluids into and out of the opening by repeated closure and opening of the opening by the fins, due to repeated peristaltic waves. This pumping effect may lead to continuous flow of fluids into and out of the opening and thus into and out of the gap of the device.

Abstract: A method and system for automatically detecting villi texture in in-vivo images. In-vivo images may be received from an in vivo imaging capsule, and at least one image may be selected for analysis. Textural details may be extracted, for example using morphological top hat transforms. The image may be divided into segments or patches. The patches may be pruned using a set of threshold conditions, which are calculated based on grayscale or color statistics of the patches. The patches may be classified as containing villi texture or not based for example on rotation-invariant textural features computed in the Fourier domain. A sum, score or rating for the image may be calculated based on the classification of each patch. The final score of the image may be averaged over a number of, for example, consecutive images, and the score may be used for detecting entry into the small bowel and segmenting the image stream to anatomical regions.
