A method and system for managing and retrieving contact information included on a plurality of business cards from a plurality of contacts of a user. The method may, for a given business card corresponding to a given contact of the user, obtain from the business card a unique identifier and a registered phone number corresponding to the contact; determine the unique identifier is associated with the registered phone number to verify the contact has been registered with a contact management server, wherein the contact management server stores contact information of the contact in association with a contact identifier comprising the registered phone number; in response to said determining, generating a record locator comprising the registered phone number and retrieving, from the contact management server, the contact information based on locating the contact identifier; and storing the retrieved contact information.

Methods and apparatus for determining brain cortical thickness are provided. One method includes determining an intensity profile at each of a plurality of cortical surface points of an imaged brain using brain tissue image data and calculating a cortical thickness based on a parametrically determined transition point of each intensity profile.

In a dose modulation method, transmission tomographic imaging data of an associated imaging subject are acquired using a radiation source (14) revolving around the associated imaging subject. During the tomographic imaging, an estimated attenuation of radiation is determined for an upcoming position or angular bin (721, 82) of the revolving radiation source based on attenuations determined at previously acquired positions or angular bins (701, 84, 90) of the radiation source. Prior to acquiring tomographic imaging data at the upcoming position or angular bin, a level of radiation produced by the radiation source is adjusted based on the estimated attenuation of radiation.

A method and system for efficient synthesis of photorealistic free-form knitwear, where a single cross-section of yarn serves as the basic primitive for modeling entire articles of knitwear. This primitive, called the lumislice, describes radiance from a yarn cross-section based on fine-level interactions, including occlusion, shadowing, and multiple scattering, among yarn fibers. By representing yarn as a sequence of identical but rotated cross-sections, the lumislice can effectively propagate local microstructure over arbitrary stitch patterns and knitwear shapes. This framework accommodates varying levels of detail and capitalizes on hardware-assisted transparency blending. To further enhance realism, a technique for generating soft shadows from yarn is also introduced.

An adaptive median filter (40) provides dynamic detection and correction of digital image defects which are caused by defective or malfunctioning elements of a radiation detector array (20). The adaptive median filter receives (100) lines of pixel values of a digital image that may have defects and a user-defined defect threshold. The lines of pixel values are scanned on a pixel-by-pixel basis using a kernel of n×n pixels, where the kernel contains the candidate pixel being examined (120). Each kernel is numerically reordered (130) and a median value is calculated (140). A defect threshold value is calculated by multiplying the user-defined defect threshold criteria and the candidate pixel value (150). A reference value is calculated by subtracting the candidate pixel value and the median value (160). The reference value is compared to the defect threshold value (170). The candidate pixel value is replaced by the median value (180) if it differs from the median value by more than the predefined defect threshold, e.g., 20%. The adaptive median filter is particularly effective in detecting and correcting double line and double column defects in digital images. In addition, the filter minimizes image blurring and maintains image resolution by filtering only defective pixels.

The present invention provides an improved finishing process and apparatus. In one embodiment, a method and apparatus are provided for finishing a metal article. The method includes cavitationally eroding the metal article to form pits in its external surface. The metal article is also corroded with a corrosion chemical to corrode the pitted metallic surface. In this manner, substantially homogeneously distributed micro-pits can be formed about the article to create a desired matte finish, as well as a surface that is amenable for sealing. In a preferred embodiment, the corrosion chemical is part of a finishing bath that is ultrasonically cavitated for eroding the metal article.

A chair includes a seat portion, a back portion and four legs supporting the combination of the seat portion and the back portion. Each of the seat portion and the back portion has two side tubes and each side tube has two flanges extending therefrom so as to define a slot between the two opposite flanges. A plurality of slats are securely fitted between the two opposite pairs of flanges of the seat portion and the back portion by bolts extending through the flanges and the slats.
