1. A method to automatically screen for the presence of a polyp in a body lumen, said method comprising:
- capturing at least one image frame from within the body lumen using a swallowable autonomous imaging device;
generating a gradient map of the at least one image frame;
automatically identifying, using a processor and the generated gradient map, an elliptical form;
comparing, using a processor, the color of the elliptical form to one or more predefined colors to differentiate between elliptical content and elliptical polyps;
comparing, using a processor, the size of the elliptical form to a predetermined size parameter; and
automatically classifying the elliptical form as content, polyp or neither in accordance with said color and size.

Abstract
An in-vivo imaging system and method to screen for colorectal polyps in the GI tract may include an in-vivo imaging device for capturing a stream of image frames in a GI tract, a polyp detector for detecting and/or identifying one or more image frames from the stream of image streams that may show colorectal polyps, and a graphical user interface (GUI) to display image frames detected.

11. A system to automatically screen for the presence of a polyp along a body lumen comprising:
-
a swallowable imaging device to provide at least one image frame of the body lumen; a polyp detector to generate a gradient map of the at least one image frame, identify an elliptical form using the generated gradient map, compare the color of the elliptical form to a predefined color to differentiate between elliptical content and elliptical polyps, compare the size of the elliptical form to a predetermined size parameter, and to classify the elliptical form as content, polyp or neither in accordance with said color and size; and a display unit. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
