International Classification:

G06K 9/00
A01K 43/00

US Classification:

382100, 382274, 356 66

Abstract:

A system for capturing and analyzing images of body features to identify treatments has a base unit with a processor and a display and an image management software component for presenting on the display a user interface to prompt a user to capture images in preselected locations on a body and to receive captured image data. The system has at least two light sources under control of the user interface that provide light following first and second light paths from the respective light sources to the plane of an imaging station, each light path having a significant portion of its light on the plane of the imaging station at a grazing angle of about ten to about thirty degrees. The first and second light paths when projected onto the plane of the imaging station intersect at an angle of at least sixty degrees. An image sensor receives light from the light sources that is reflected from the surface of a body feature located at the imaging station and produces pixel image data representing the body feature. A rating software component receives the pixel image data from the image sensor and is configured to mimic the judgment of a dermatologist to provide a rating vector representing the condition of three or more attributes of the body feature represented by the pixel image data.

International Classification:

H04N 521
H04N 1700

US Classification:

348180

Abstract:

Video cameras, such as charge coupled device cameras, are used for optically making spatial measurements. For example, such cameras are used for laser beam analysis. Such cameras also have drawbacks including baseline offset error and poor signal-to-noise ratio. By adjusting the baseline so that both noise and the desired signal produce only positive digital counts, deriving a baseline offset level with only noise, and then subtracting the baseline offset level from subsequent frames Containing data representing both noise and the desired signal, the baseline offset is corrected. With the baseline offset being corrected, signal-to-noise ratio improving techniques, such as frame averaging and results averaging, can be applied to extract the desired signals which would otherwise be buried in the noise. The method and apparatus is particularly suited to laser beam performance evaluations.

Abstract:

Video cameras, such as charge coupled device cameras, are used for optically making dimensional measurements of laser beams. Such cameras have drawbacks including baseline offset error, shading error, pixel-to-pixel fixed pattern offsets, and poor signal-to-noise ratio. Methods and apparatus to correct for these errors, without losing any desired signal components, wherein the baseline offset error is corrected without the loss of any signal components that may otherwise be obscured due to noise. The baseline of the signal is raised above a digitizer's zero level, an average baseline without an input signal present is determined, and then the average baseline is subtracted from the subsequently obtained signals. The subtraction process is performed such that the subsequent frames in memory retain all negative signal components, as well as positive signal components, and thus there is no loss of the desired signal. Any subsequent quantitative measurements consider both the positive and negative signal components and thus measurements are made as accurately as possible.
