Abstract: Systems, methods, apparatus, and computer program products are provided for determining the scale of an image. In one embodiment, an image is received for analysis. The image may include a token with (a) a known height, (b) a known width, and (c) a known color value based on a color model. Pixels that are within a predetermined threshold of the known color value of the image are identified. After identifying the pixels, a cluster of pixels that substantially includes the token is identified. With the known size of the token and the pixels in the token identified, the scale of the image can be determined.
