1. A method for analyzing a surgical textile, the method comprising:
capturing a first depth image of a field of view at a first time;
detecting a shape of the surgical textile in the first depth image;
indexing a frame counter upon detecting the shape in the first depth image;
capturing a second depth image of the field of view at a second time succeeding the first time;
detecting whether the shape of the surgical textile appears in the second depth image; and
indexing, based on the detecting of whether the shape of the surgical textile appears in the second depth image:
the frame counter upon detecting that the shape appears in the second depth image; or
a non-detection counter upon detecting that the shape of the surgical textile does not appear in the second depth image.
