Segmentation of a product markup image based on color and color differences

A non-transitory computer-readable storage medium comprising one or more sequences of instructions which when executed by one or more processors cause the one or more processors to perform:

• receiving an input image of a customizable product comprising markup;
• partitioning the input image into a plurality of image regions based on color, wherein the partitioning comprises:
• assigning a color difference value to each location of a plurality of locations within the input image, wherein a particular color difference value assigned to a particular location is determined based in part on the input image and indicates how different a color of the particular location is from colors of other locations neighboring the particular location;
• assigning each location of the plurality of locations to an image region of the plurality of image regions according to a particular order, wherein the particular order is based at least in part on color difference values associated with the plurality of locations;
• selecting a particular image region for assignment to a location based in part on the color of the location, wherein the color of the location is determined based at least in part on the input image;
• identifying data representing at least a particular portion of the markup in the input image based on the partitioning;
• causing use of the data representing at least a particular portion of the markup in any of a visualization of the customizable product or a manufacturing control associated with the customizable product.
