Disclosed are systems and methods for providing video content while inhibiting the copying of that content for later viewing. Video images may be made difficult to copy for presentation at later times by the omission or addition of content developed in relation to the particular initial viewing. For instance, video information may be customized by omitting information that is not likely to be substantially perceived by the initial viewer but that is substantially likely to be perceived as missing by at least some other viewers. As another example, video information may be customized for a particular viewing instance so that it contains modified, selected or injected information that is likely to be perceived as non-disruptive or unnoticeable by the original viewer but that would be perceived as substantially noticeable and / or disruptive by some other viewers, including when parts of more than one such video information are combined in an effort to remove customization related to their respective original viewings. Various means and methods for accomplishing the forgoing in a variety of settings are disclosed including also for providing privacy related to what is viewed. In some examples higher-resolution images are provided for the region near the viewer's point-of-regard and lower resolution images are provided elsewhere, which also has the effect of reducing the bandwidth required. For interactive content rendered from digital models, a model for a central foveal region may be provide greater detail and have greater computational requirements than a model for a peripheral view, providing both economy / performance in rendering and protection against copying.

A stent may be manufactured by providing a tube having a longitudinal axis therethrough, providing a stationary source of laser radiation, generating a beam of laser radiation using the source of laser radiation, and cutting a desired pattern into the tube by scanning the beam over a desired region of the tube.

The invention discloses an electronic map data storage and query method, device and system. The electronic map data storage and query method comprises the following steps of: grading the map source data into a plurality of grades according to the sizes of proportional scales, and setting a proportional scale grade threshold; storing the map data, of which the proportional scale grade is not higher than the threshold, according to a raster data format; and storing the map data, of which the proportional scale grade is higher than the threshold, according to a vector data format. In the technical scheme provided by the embodiment of the invention, the map data is stored according to two modes including a raster data mode and a vector data mode, so as to give consideration to the requirements on two aspects of exhibition effect and performance of the electronic map on a mobile terminal.

The invention belongs to the field of computer vision, and provides good detail while improving image contrast, and the natural performance of the tone is kept while the noise is suppressed. An underwater image enhancement method based on structure-texture layering comprises the steps of firstly, carrying out color correction through histogram equalization, decomposing the image subjected to colorcorrection into a low-frequency structural layer and a high-frequency texture layer, leaving the noise on the texture layer, accurately estimating the transmission rate from the structural layer without noise based on a proposed fog line model to conduct enhancement processing, enhancing the texture layer by using a gradient residue minimization method, reconstructing the reinforced structural layer, the texture layer and the refined edge mask to form a final enhanced image through scaling, so that the problems that can not be solved through existing technology is solved. The method is mainlyapplied to underwater image enhancement and processing occasions.

A fastening element in the form of an eye bolt, which has a ring body encompassing a ring opening. The ring body is connected with an end area of a fastening bolt, which has, at a distance from said end area, in its fastening position, balls with a part of their surface protruding from the surface shell of the fastening bolt. The balls are held in their fastening position by a bolt element guided within the fastening bolt. The bolt element is axially longitudinally moveable against the force of a spring and is intended to provide a solution which improves the characteristics of use and handling of such an actuation element. This is achieved by the fact that the ring body is extended in the manner of a shackle beyond its ring opening and the end area of the fastening bolt is fixed so as to pivot between the shackle ends.

An image processing method and device is configured to convert an obtained image to be processed into a grayscale chrominance YUV mode image; determine an equilibrium mapping curve of a whole grayscale image according to the grayscale image in the YUV mode image; divide the whole grayscale image into a plurality of sub-regions, and determine a mapping restriction parameter for each pixel in each of the sub-regions; adjust a grayscale value of each pixel in the grayscale image according to the determined equilibrium mapping curve of the whole grayscale image and the mapping restriction parameter of each pixel in each of the sub-regions; and convert the adjusted grayscale image into an image of original mode. an image is processed using an equilibrium mapping curve and a plurality of mapping restriction parameters present the image details well and greatly reduce the calculation amount.
