1. A computer implemented method, comprising: accessing a set of images within a video stream; identifying an object of interest in one or more images of the set of images, the object of interest having a first portion and a second portion; detecting a region of interest within the one or more images; generating one or more binarization matrices from the one or more images; determining a pixel radius; filter the one or more binarization matrices to exchange a first pixel value for a second pixel value where a pixel associated with the first pixel value is proximate to a set of pixels of the second pixel value, based on the pixel radius; identifying a first thickness and a first set of median pixels of the first portion and a second thickness and a second set of median pixels of the second portion; determining a polyline approximating the first portion and the second portion of the object of interest; and generating a model for the polyline.
