Method for determination of wireless terminals positions and associated system and apparatus thereof

Abstract: Conventional position estimation methods require the deployment of more fixed anchors in order to increase the accuracy in a crowded indoor environment, or they suffer from inaccuracies due to multipath fading. The present invention overcomes the problems associated with the prior arts by selecting one or more mobile nodes as virtual anchors when estimating the position of a target mobile node. This takes advantage of the fact that mobile nodes are closer to the target mobile node than the access points in most typical deployments, thus eliminating the need to deploy more access points or fixed anchors for the purpose of position determination. After obtaining an initial estimate of the position of the target mobile node, the target mobile node can serve as virtual anchors to estimate the positions of other mobile nodes, which can then be used to further refine the position estimate of the target mobile node.

Method and apparatus for removing noise in still and moving pictures

Abstract: A method for filtering a blocky noise, as well as ring and mosquito noise, from still and moving pictures is disclosed. The method has the steps for locating a block boundary in the picture and selecting pixels on one side of the block boundary as a first group and pixels on the other side of the block boundary as a second group, calculating mean values (m1, m2) and deviation (c1, c2) of the pixels in each of the first and second groups, detecting whether or not the deviations (c1, c2) are smaller than a predetermined threshold value (T2), applying a first predetermined filtering (equations (5), (6)) when the deviations (c1, c2) are not smaller than a predetermined threshold value (T2); and applying a second predetermined filtering (equations (7), (8)) when the deviations (c1, c2) are smaller than a predetermined threshold value (T2).

Image rendering device, image rendering method, and image rendering program for rendering stereoscopic panoramic images

Abstract: An image rendering device realizes stereoscopic viewing of composite images generated by compositing background three-dimensional models and foreground three-dimensional models each defined in three-dimensional modeling space A texture mapping unit converts background image data into two or more viewpoint textures and maps each viewpoint texture to a background three-dimensional model in the three-dimensional modeling space A viewport conversion unit extracts, for each of the two or more viewpoint textures, a viewport image from the background three-dimensional model mapped with the viewpoint texture and from the foreground three-dimensional model By comparing a parallax of the foreground three-dimensional model occurring in stereoscopic playback with a parallax of the intra-texture object occurring in stereoscopic playback, the device determines depth relationship between the foreground three-dimensional model and the intra-texture object and adjusts positional relationship between the foreground three-dimensional model and the intra-texture object based on a result of the determination

High-frequency module and method for manufacturing the same

Abstract: In the high-frequency module of the present invention, an insulating resin is formed so as to seal a high-frequency semiconductor element mounted on a surface of a substrate and further to seal electronic components. Furthermore, a metal thin film is formed on the surface of the insulating resin. This metal thin film provides an electromagnetic wave shielding effect.

Information embedding method, information extracting method, information embedding apparatus, information extracting apparatus, and recording media

Abstract: An apparatus for embedding secret information in an image signal transmitted with a shape signal showing the shape of an object is described. This apparatus comprises an embedding position decision unit for deciding a position in the object where the secret information is to be embedded, according to the shape signal; and a compositor for embedding the secret information in the position decided by the decision unit. Therefore, the secret information is protected against translation or clipping of image.
