The application of a virtual dental patient with dynamic occlusion during esthetic restoration in digital workflow is described. An intraoral scanner, facial jaw motion analyzer, and cone beam computed tomography were used to transfer data construct the patient. With aid patient, predictability accuracy can increase throughout treatment, simplifying clinical evaluation prosthesis adjustment imp...

Fabricating a complete denture in conventional manner may be complicated and difficult. The purpose of this article was to describe the benefits fully digital workflow fabrication procedure dentures based on impressions edentulous jaws. data for were acquired using an intraoral scanner then used design base teeth. resulting exported 3D printer or milling machine fabrication.

Advancing technology has made document image processing an important feature in automation of office documentation. Digital filing system save space, paper and printing cost. The problem arises when document to be read is not placed correctly in scanner, which leads to the miss interpretation of document and increases the storage space .This paper deals with extraction of text from those skewed...

A procedure for an automatic search and measurement of artificial targets in digital images for elose-range photogrammetric applications is presented. Photographs taken with a sem i metric 6x6 camera were digitized by the "ASTROSCAN" at the Sterrewacht Leiden. The especially designed targets contain a circular barcode for automatic identification. It is shown that this procedure improves both p...

The French Ophthalmology Society (SFO) elected as its annual reporter E. Hartmann on "Radiography in ophthalmology. A clinical atlas" (1936), then H. Fischgold et coll. (1966) for "Neuroradiological exploration in ophthalmology" and, for 1996, the author of this article, for "Imaging in ophthalmology," the 3rd phase in this 30 year cycle, due to chance and the need for the development of X-rays...

This case report describes the fabrication of monolithic all-ceramic restorations using zirconia-reinforced lithium silicate (ZLS) ceramics. The use of powder-free intraoral scanner, generative fabrication technology of the working model, and CAD/CAM of the restorations in the dental laboratory allows a completely digitized workflow. The newly introduced ZLS ceramics offer a unique combination ...

It is the dream of every digital imaging operator: dealing with a picture that always looks the same, regardless of the processing device: scanner, monitor or printer. Absolute consistency is impossible to achieve, due to objective limitations with colors that each device can render and/or process, but high quality results can be obtained with a color management system that is up to the job; an...

Ž . This study employed an airborne laser scanner to detect changes of buildings by acquiring a digital surface model DSM data of urban areas. Simple comparison between DSM data sets acquired at different occasions successfully detected building changes without omission errors. A CCD array image simultaneously acquired with the DSM data was also automatically orthorectified with the DSM data an...

In recent years a variety of 3D scanning technologies has been applied to the field of Heritage Preserve. The paper describes an operational 3D scanning system that has been set up at Kaohsiung Museum of History for digital archival of cultural artifacts. Also, an approach that refines resolution of stereo correspondence to improve model quality obtained by structured lighting is proposed. The ...

The registration and geometric recti cation of airborne scanner imagery is an essential prerequisite for the processing and analysis of this type of images. The Digital Photogrammetric Assembly (DPA) is an airborne camera consisting of three pan-chromatic line arrays for stereo imaging and four line arrays for multi-spectral imaging. For georeferencing the sensor system is completed by a module...
