A facial recognition system that captures a plurality two-dimensional images of a target face, creates a three-dimensional facial model from the plurality of two-dimensional images of a target face, moves the three-dimensional facial model to a predetermined pose orientation to result in a normalized three-dimensional facial model, extracts measurements from the normalized three-dimensional facial model, and compares the extracted measurements to other facial measurements stored in a data base. Measurement extraction can be enhanced by modifying the data format of the normalized three-dimensional facial model into range and color image data.

A device capable of capturing and facilitating the removal of a thrombus in blood vessels (or stones in biliary or urinary ducts, or foreign bodies) uses a soft coil mesh with the aid of a pull wire or string to engage the surface of a thrombus, and remove the captured thrombus. The soft coil mesh is formed by an elongated microcoil element that forms the helical elements of a macrocoil element. The microcoil element provides a relatively elastic effect to the helical elements forming the macrocoil and allows for control of gripping forces on the thrombus while reducing non-rigid contact of the device with arterial walls. The use of multiple coil mesh elements, delivered through a single lumen or multiple lumens, preferably with separate control of at least one end of each coil, provides a firm grasp on a distal side of a thrombus, assisting in non-disruptive or minimally disrupted removal of the thrombus upon withdrawal of the device.

The invention relates to a method and apparatus for color matching of slightly colored objects which are transparent, diffusing an absorbent, by acuminating a small error of the objects with a first bunch of optical fibers. A second bunch of optical fibers is used to pick up the light back scattered from the area of the objects. The second fibers are located inside of the illuminating fibers. The light is measured at 3 wavelengths that correspond to blue, green and red colors and the pigmentation of the object is calculated as a difference between the red and blue spectrum components. Presentation of the brightness is calculated to be proportional to the green spectrum component. The pigmentation and brightness is then compared with the same perimeters of a standard shape pallet. The invention is particularly suitable for color matching the teeth in the mouth with dental prosthesis and dental restorative materials.

A system and method reduces the amount of variation in a fingerprint image due to distortion from elastic deformation of the finger surface and projection onto a planar coordinate system. The amount and extent of distortion is estimated, and the process is inverted in a systematic way, so that the amount of distortion is minimized, and the distortion present is consistent, so that different images of the same print will have very similar distortion and thus matching of the fingerprints will be reliable and unaffected by the distortion.

A new technique for identifying from images a camera, or other imaging device such as a scanner, is based on the device's reference noise pattern, a unique stochastic characteristic of all common digital imaging sensors, including CCD, CMOS (Foveon™ X3), and JFET. First, one determines from images the sensor's reference pattern noise, which uniquely identifies each sensor. To identify the sensor from a given image, the presence or absence of the reference pattern noise in the image under examination is established using a correlation detector or other means.

A system and method of selecting products and services for an audience likely to purchase such products and services utilizes a collection of data reflecting, for individual consumers, a history of purchases, and retention or return of such purchases. For individual consumers, subsets of consumers are created whose tastes correlate positively and negatively with the individual consumer. Lists are created of products for a target consumer based on the likes of the subset positively correlating and the dislikes of the subset negatively correlating. Recommended products are offered with a financial incentive such as a money back guarantee which serves the dual purpose of inducing the purchase as well as providing the purchase and return data needed in the data collection.
