Abstract
Systems and methods for de-smoking images of a surgical scene are described. Methods include receiving a video of a surgical scene including an image frame. Methods include determining that the image frame includes a smoke occlusion. Methods include determining an estimated un-occluded color of one or more pixels of the image frame using a lookup table, the lookup table mapping between a color space and a set of color bins including the estimated un-occluded color. Methods include determining a respective estimated true color for the one or more pixels of the subset using the imaged color, the estimated un-occluded color, and the smoke color. Methods also include generating a de-smoked image frame using the respective estimated true colors of the one or more pixels, the de-smoked image exhibiting a reduction of the smoke occlusion relative to the image frame.
