1. A system for masking endoscopic images, the system comprising one or more processors configured to:
receive an input digital image;
apply one or more contour detection algorithms to the digital image to detect a plurality of contours in the digital image;
identify, among the plurality of contours, a contour having the largest area;
estimate a circular area of the image enclosing the contour; and
generate a masked digital image by applying a mask to the input digital image, wherein the mask is based on the estimated circular area.
