Claim One:
1. A method for detecting a transition in an image stream captured within a body lumen by an autonomous in viva device inserted into said body lumen, said device comprising an imager and designed to pass through said body lumen and to capture a stream of images thereof, the method comprising: receiving a first image and a second image of the image stream captured using said imager during a single pass of said autonomous device through said body lumen, wherein the first image and the second image correspond to first and second chronological points in time; computing, using a computer, values of a structure related parameter of the first image and of the second image, wherein the structure related parameter is the presence or absence of a villi structure detected using image based edge detection algorithms; and identifying a transition in the values of at least the structure related parameter between the first image and the second image.
