Abstract: De-ringing operation for image processing. A selective image processing means is presented herein by which high frequency content is preserved while also eliminating ringing within digital images, and this is achieved without introducing aliasing. Based on the analysis of neighboring pixels, one or more of multiple filter modules and/or multiple image filtering/rocessing means is/are selectively applied to generate an output sample for a given pixel location. Two measures (e.g., local activity (LA) and edge strength (ES)) are calculated based on processing at least two different groups of pixels near a desired output sample. One of these groups of pixels may be a subset of another of the groups of pixels. By analyzing these two measures (e.g., LA and ES), selective processing of pixels near the desired output location ensures that high frequency content within the digital image is preserved with substantially reduced and/or eliminated ringing therein.

Abstract: In a video processing device, scale of a video image is detected for vertical and horizontal directions based on pixel information, for example, per pixel vertical and horizontal gradients. Gradients are utilized or discarded based on picture format, standard deviation of luma levels and pixel location relative to black border edges, graphics and/or overlaid content. Mosquito noise filters are adapted based on scale and/or noise strength. Median and/or linear filter results are selected based on a weakest, a strongest and/or a blended result. Horizontal and vertical operations are performed separately for edge detection, edge strength determination, filtering and filter correction control. Horizontal and vertical block grid spacing and grid shift are determined. Block noise strength is determined. Block noise filters are configured based on scaling and/or noise strength. Filter corrections are limited based on block noise strength. Noise reduction results may be blended to generate a pixel correction value.

Abstract: To determine a coefficient of diffusion of a radioisotope in a radioisotope-containing implant structure and to calculate a quantity of radioisotope to be introduced in an implant structure in view of administering to a vascular region of a patient's body a dose of radioactivity at a given dose rate, a relation is calculated between a coefficient of diffusion of the radioisotope in the implant structure and a coefficient of diffusion of the radioisotope in the vascular region of the patient's body for at least one given period of time during which the radioisotope has to be released. The diffusion coefficient of the vascular region is determined. The method also determines, from the diffusion coefficient of the vascular region and in connection with the above relation, the diffusion coefficient of the implant structure required to release the radioisotope within the given period of time.

Abstract: The invention is concerned with a substantially nitrogen-free process for chloride-route TiO.sub.2 pigment manufacture in which a TiO.sub.2 -containing feedstock is subjected to a fluidized-bed, high temperature carbochlorination in a chlorinator to produce TiCl.sub.4 which is thereafter converted to TiO.sub.2 by oxidation. The TiO.sub.2 -containing feedstock and a solid carbonaceous reducing agent are fed to the chlorinator under a CO.sub.2 blanketing atmosphere such that the carbochlorination is carried out in a substantially nitrogen-free atmosphere containing CO.sub.2 and a CO.sub.2 -rich flue gas is generated, the CO.sub.2 in the chlorinator assisting in controlling thermal balance of the carbochlorination reaction. The absence of significant concentrations of nitrogen in the flue gas results in a favorable condition enabling either or both the CO and CO.sub.2 contained in the flue gas to be readily recovered, purified and sold as by-products.
