1. A computer-based method for performing de-identified location analytics, comprising the steps of:
receiving a building arrangement image, wherein the building arrangement image has one or more rooms and one or more identifiable characteristics;
generating a de-identified image by removing the identifiable characteristics from the building arrangement image;
generating a binary threshold image by processing the de-identified image using a threshold process, wherein the binary threshold image comprises one or more segmentation objects;
generating a segmentation image by removing any segmentation objects with an area less than a defined pixel area from the binary threshold image;
extracting a set of room definitions from the segmentation image via region of interest processing, wherein each room definition comprises a series of pixels corresponding to an outline of one of the rooms of the building arrangement image;
generating a pixilation table, the pixilation table comprising one or more room definition entries corresponding to the room definitions of the segmentation image, wherein each pixel of the segmentation image is mapped to the room definition entry corresponding to the room definition of the outline surrounding the pixel in the segmentation image; and
assigning a label to each room definition entry of the pixilation table.
