Abstract: A fluorescence standard for identifying variations in illumination during imaging has a composite fluorescent laminar structure, which fluoresces in response to light in the approximate wavelength range of 375 nm to 430 nm. The fluorescent object has at least two areas with different fluorescent response, e.g., a first made from a strongly luminescing material, such as GG420 filter glass. A portion of the GG420 glass is covered by filter glass having an attenuating effect on the fluorescent response. In accordance with a method of the present invention, variations in illumination during imaging with a camera are detected by placing the standard before the camera during imaging. Each captured image may contain the image of the standard and the fluorescent response of the standard in different images can be compared to identify any response changes due to variations in illumination. The variations in illumination can then be remediated by adjusting the source of illumination, the camera or ambient lighting.

Abstract: An apparatus and method for identifying facial regions in an image includes a computer running a program that tests pixel values of an image to identify objects therein having attributes like pupils, such as shape, size, position and reflectivity. To reduce the time to identify pupils, the image is sub-rected, sub-sampled and only one color/brightness channel is tested.

Abstract: An imaging station for taking a plurality of digital images of a subject under a plurality of illuminating conditions and storing and analyzing the digital images, includes a housing, containing the digital image capturing apparatus, like a camera or video recorder, a computer for processing the image data and one or more displays for displaying images of the person. The imaging station aids in controlling lighting during image capture and may be used to optimally position the subject for imaging. The computer may be programmed to conduct various image processing functions and may be networked to allow image sharing. A display which may be provided on the exterior of the housing allows an operator to visualize the subject and to control the imaging process. The imaging station may be used for teaching purposes.

Abstract: An imaging system and method has digital image capture and analysis capability. The digital images may be taken in a variety of illumination conditions, with the skin response indicating skin condition. The digital images may be converted from RGB format to L*a*b* format and analyzed quantitatively to assess color and brightness. The color/brightness information from the digital images may be used to assess skin condition and changes thereof, as well as selecting cosmetics provided in a range of colors. The color information gleaned from the digital images of a population may be utilized to identify a palette of colors for cosmetics or to aid in conducting clinical studies.
