Abstract: A system includes a camera, a weigh-in-motion scale, and a processor. The camera is configured to capture one or more images of a vehicle as the vehicle goes over the weigh-in-motion scale. The weigh-in-motion scale is configured to generate one or more weight measurements of the vehicle as the vehicle goes over the weigh-in-motion scale. The processor is operatively coupled to the camera and the weigh-in-motion scale. The processor is configured to determine an acceleration of at least a portion of the vehicle based at least in part on the one or more images of the vehicle. The processor is also configured to adjust at least one of the one or more weight measurements based on the acceleration.

Abstract: An apparatus and method for estimating the power spectral density of an unknown illuminant that does not require direct spectral measurements. The apparatus and method allows calibration of color images taken with commercially available digital cameras in arbitrary illumination. Besides an imaging system, a digital computer, a means for transferring image information from the imaging system to the digital computer, and software to carry out the method, the only additional equipment a photographer needs is a set of color standards.
