Person Identification With Dental Images By Striae Patterns In Radiographs

The Identification of people using their dental records, mainly as radiograph images searches the database of Postmortem (PM) and antemortem (AM) radiographs to determine the identity of the person associated with the PM image. We use a semi-automatic method to extract shapes of the teeth from the AM and PM radiographs, and find the affine transform that best fits the shapes in the PM image to those in the AM images. The shape extraction is a difficult problem for dental radiographs, especially for poor quality images where some tooth contours are indiscernible. Fortunately, the radiographs not only give us the information about the shape of the teeth, but also other information such as the artificial prothesis of the teeth, the striae patterns and trabecular patterns developing an image restoration algorithm to handle poor quality radiographs. The proposed format is to work similar to the synthesis algorithm of diatoms where the striae are formed gradually, the ones near the centre of the diatom start growing first and may be partially completed by the time the striae further away from the centre start forming. The attempt is to model this process similar to iterative synthesis algorithm of diatom.

Pros and Cons of RFID Technology

In the late 1990's demand for RFID increased once companies saw the advantages of RFID, as compared to the simple bar-code. The RFID tag stored all the necessary information about a given pallet, box or product and was readable without line of sight. The time saved checking in shipments and waiting around for shipments to arrive decreased significantly. RFID enables companies to save money by utilizing time more efficiently. EPCGlobal was established in 2003 to offer a set of standards on use of Electronic Product Code. Retail stores using RFID can decrease out-of-stock items, as well as being more informative when talking to customers about product information and product arrival dates. For producers and consultants of the technology, a lot of money is being made with new breakthroughs, cheaper RFID prices and new applications of the technology. Companies can stand to gain and lose with companies using RFID, as companies can now do research on a product level with RFID possibly invading consumer’s privacy rights. If RFID stayed only on larger ticket items and on pallets and boxes consumers would enjoy the technology as it makes their shopping experiences go smoother.

Data Fiber Optics – Light Speed Transmission

Why settle for slow speed, high electricity costs and a technology invented a hundreds years ago if you can have the latest in data transmission at less the cost and many times the speed? With the use of glass or plastic threads to transmit data the fiber optics is an upcoming technology. A bundle of glass threads capable of transmitting messages that are transformed into light waves is what makes the data fiber optics. Sharing a variety of technical details in the flowing article, I hope to make you have a better understanding of the subject of fiber optics. The functions will be demonstrated by explaining how the technology uses light energy to provide information and data to a variety of sources.
