摘要:
Systems and methods of utilizing communications networks and multivariate analysis to predict or recommend optimal products from a predefined population of commercially available products are disclosed. The recommendations are based on intelligence contained in processing elements and subjective and/or objective product information received from consumers or input to the systems as part of their initial setup. The output of the systems comprise sets of products that they predict the consumer will prefer and/or perform well for the problem or concern identified by the consumer. The performance and preference predictions are a function of consumer problems and product responsiveness patterns. Objective product information is generally obtained with diagnostic instruments. Data measured with the diagnostic instruments may be communicated to the data processing portions of the invention via the Internet. The outputs of the data processing portion of the system may be presented to consumers via the Internet as well.

A self-contained, portable apparatus and corresponding method for capturing, displaying and analyzing images of a person includes a housing for containing a digital camera, a light source capable of providing at least two different wavelengths of light, a touch-screen display and a computer for controlling the camera, the light source and the display. The apparatus selectively captures and displays a plurality of digital images using different wavelengths of illuminating light. The light source may include a plurality of flashes and filters, some of which may be adjustable to adjust the angle of incidence of the illuminating light on the subject. Preferably, the apparatus is self-serve, allowing any person to capture, review and analyze the images. To that end, the apparatus may provide a moving image and verbal instructions to a user to aid in positioning themselves relative to the camera. Instruction may further be provided by text or internet connection for using the apparatus and/or interpreting the captured images. An intuitive graphic user interface with thumbnail images is employed. Focus control, zoom and synchronized side-by side comparison of images are available.

摘要:
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. Alternatively, the images can be normalized through digital image processing.
