Patent ID: 8422755

Claim:
A system for comparing sequences of in vivo images, the system comprising: a memory to store a plurality of template sequences each associated with a different set of pre-defined intestinal motility characteristics; a processor to: retrieve a template sequence from the memory, receive in vivo images captured by an autonomous in vivo imaging device, and divide the captured in vivo images into a plurality of captured image sequences, wherein for each of the plurality of captured sequences, the processor is to: assign a first set of scores to each frame in the captured sequence, wherein each score in the first set of scores is based on a comparison of anatomical structures of the frame in the captured sequence and anatomical structures of a frame in the retrieved template sequence; assign a second set of scores to each frame in the captured sequence, wherein each score in the second set of scores is based on a comparison of a change in anatomical structures between the frame in the captured sequence and a frame in the captured sequence consecutive thereto and a change in anatomical structures between a pair of consecutive frames in the retrieved template sequence; and align each frame in the captured sequence with one or more frames in the template sequence for which the comparisons therebetween generate the minimum scores in the first and second sets of scores, and wherein for the plurality of captured image sequences, the processor is to: define a match between the template sequence and one or more of the plurality of captured sequences if the combination of scores in the first and second sets of scores for the frames in the captured sets compared with the one or more aligned frames in the template sequence is below or above a threshold value; and a display to display the captured in vivo images, in sequence, as a moving image stream.
