1. A computer-implemented method, comprising:
obtaining, by one or more processors, input data comprising an image and image data comprising coordinates defining a region of interest in the image, wherein each coordinate defines a point on the image, wherein the image comprises pixels;
determining, by the one or more processors, a sequential order for navigating the coordinates defining the region of interest, wherein the sequential order is non-duplicative of any coordinate of the coordinates;
defining, by the one or more processors, a set of points comprising a border around the region of interest, wherein the defining comprises supplementing the coordinates comprising points in the image by adding additional points comprising intersection points, wherein each intersection point is an intersection of a line between two coordinates of the coordinates with an edge of a pixel of pixels in the image, wherein the coordinates comprising points and the intersection points comprise the set of points;
determining, by the one or more processors, a combined area of sub pixel subregions in each pixel comprising one or more points in the set of points, the determining comprising:
identifying, by the one or more processors, one or more points of the set of points on the pixel;
generating, by the one or more processors, based on the one or more points, one or more sub pixel subregions, wherein each sub pixel subregion comprises contiguous points of the set of points, wherein the contiguous points are within or on the pixel; and
utilizing, by the one or more processors, the one or more sub pixel subregions to determine the combined area of sub pixel subregions.
