System and method for detection of in-vivo pathology sequences

A system to automatically detect a pathology frame sequence in an image stream captured in a body lumen, the system comprising:

• a storage unit to store an image stream, the image stream comprising a plurality of image frames captured in the body lumen, and to store a pathology score for at least a portion of the image frames, the pathology score correlating to a probability that at least one pathology candidate is depicted in an image frame;
• and
• a processor configured to:
• select, based on the pathology score, a seed frame from the image stream which is likely to include at least one pathology candidate;
• select a pathology candidate in the seed frame;
• and
• track the pathology candidate in consecutive image frames adjacent to the seed frame in at least one of a forward direction or a backward direction with respect to the time of capture of the image frames, to identify a sequence of image frames adjacent to the seed frame and which comprises the pathology candidate.

A method for detecting a pathology frame sequence in an image stream captured in a body lumen, the method comprising:

• receiving an image stream comprising a plurality of image frames captured in a body lumen;
• selecting a seed frame from the image frames, the seed frame being an image frame that is likely to include at least one pathology candidate;
• selecting a pathology candidate in the seed frame;
• and
• tracking the pathology candidate in consecutive image frames adjacent to the seed frame in at least one of a forward direction or a backward direction with respect to the time of capture of the image frames, to identify a sequence of image frames adjacent to the seed frame and which comprises the pathology candidate.
