1. A method comprising:
generating, by a computing device, via an image capture device of the computing device, an image of a portion of a textile;
determining, for each pixel of a reference image of a reference textile, a reference value indicative of a pile height;
determining, for each pixel of the image, a value indicative of the pile height;
determining, for each pixel of the image, a variation between the reference value and the value;
determining, based on the one or more variations between the one or more reference values and the one or more values, one or more height variations between the textile and the reference textile; and
performing, based on at least one height variation of the one or more height variations satisfying a threshold, an action.
