Abstract:
Pill endoscopy cameras generate hours-long videos that need to be manually inspected by medical specialists.
Technical limitations of pill cameras often create large and uninformative color variations between neighboring
frames, which make exploration more difficult. To increase the exploration efficiency, we propose an automatic
method for joint intensity and hue (tone) stabilization that reduces such artifacts. Our method works in real
time, has no free parameters, and is simple to implement. We thoroughly tested our method on several real-world
videos and quantitatively and qualitatively assessed its results and optimal parameter values by both
image quality metrics and user studies. Both types of comparisons strongly support the effectiveness, ease-of-use,
and added value claims for our new method.
