Abstract: A method for forming an enhanced image of tooth tissue for caries detection obtains fluorescence and reflectance image data from a tooth. Each pixel in the fluorescence image data is combined with its corresponding pixel in the reflectance image data by subtracting an offset to the reflectance image data value to generate an offset reflectance image data value, and then computing an enhanced image data value according to the difference between the fluorescence image data value and the offset reflectance image data value, whereby the enhanced image is formed from the resulting pixel array of enhanced image data values.

Abstract: Systems and methods for determining the speed of a vessel from an overhead image of the vessel's wake can include the initial step of defining a cusp line for the wake. A representative line segment from the defined cusp line that is suitable for building an image intensity profile for the image can be selected. Once the intensity profile is built along the line segment, the wake wavelength ?cusp from the image intensity profile can be found by measuring the distance between successive points of intensity maxima (or successive intensity minima points) along the line segment. Once ?cusp is found, the vessel speed can be determined from the images according to the formula ?ship=?{square root over (1.352*?cusp)}. The systems and methods can be practiced using any overhead imagery systems that display a vessel's wake, including synthetic aperture radar (SAR) and electro-optical (EO) overhead imagery systems.

Abstract: A method and apparatus is disclosed for tracking an arbitrarily moving object in a sequence of images where the background may be changing. The tracking is based on visual features, such as color or texture, where regions of images (such as those which represent the object being tracked or the background) can be characterized by statistical distributions of feature values. The method improves on the prior art by incorporating a means whereby characterizations of the background can be rapidly re-learned for each successive image frame. This makes the method robust against the scene changes that occur when the image capturing device moves. It also provides robustness in difficult tracking situations, such as when the tracked object passes in front of backgrounds with which it shares similar colors or other features. Furthermore, a method is disclosed for automatically detecting and correcting certain kinds of errors which may occur when employing this or other tracking methods.

Abstract: To provide a registration apparatus, a collation apparatus, an extraction method and an extraction program capable of improving authentication accuracy. An image signal obtained by imaging a biometric subject in a predetermined biological position is subjected to predetermined processing so as to extract a feature portion of the biometric subject in the image signal. The feature portion is subjected to Hough transform. Parameter extraction is performed by changing the extraction condition such that the number of parameters obtained by the Hough transform becomes a predetermined value. In the case where the value of the extraction condition at the time point when the number of parameters is the predetermined value falls within a range from the upper limit set value to the lower limit set value, the predetermined number of parameters are set as registration data or data to be collated with the registration data.
