Abstract:
1. A method using a processor on a computer device for increasing the accuracy of recognition of an object within an image, comprising: including a single target device that is calibrated to predetermined properties within the image prior to capturing the image; wherein the image is a digital image and wherein the target device is illuminated with a light source; wherein the target device is placed at any location within a field of vision of a camera capturing the image; determining lighting attributes associated with the target device directly from the digital image; wherein the lighting attributes determined comprise a light direction, a light diffusion, and a light ambiance; associating the lighting attributes of the target device with the object such that lighting attributes applied to the object are determined; generating a contour mapping of the object using light reflected from the object adjusted for lighting conditions determined from the lighting attributes of the target device; wherein the target device is located at a position that is different from a position of the object such that the contour mapping of the object is generated in response to lighting attributes associated with a different object; wherein the position of the target device and the position of the object are not coincident; and associating the contour mapping with the image, such that the contour mapping uniquely identifies the object within the image.
