摘要:
An electronic confidential document viewing method is performed by an electronic device in electronic communication with a pair of eyeglasses. In response to display a confidential document on a display device, a protection image is generated based on a security image of the confidential document. The protection image is a copy of the security image that is offset from the security image by a predetermined distance in a vertical direction or a horizontal direction. The security image and the protection image are synchronously transmitted to the display device. The display device displays an overlapping picture based on the two images. The eyeglasses receive the overlapping picture, and separate the overlapping picture into two images. One of the two images is viewable by the left eye of a viewer, and another image is viewable by the right eye of the viewer.

A display device with a plurality of display portions; each display portion being a television or areas of a screen of a television. The display device can be controlled by a control device such as a portable device which includes a touch-sensitive display unit and a control unit. The touch-sensitive display unit displays a graphic user interface (GUI) corresponding to the display device. The control unit produces operation parameter(s) according to touch operation(s) on the touch-sensitive display unit and transmits the operation parameter(s) to the display device, thereby enabling the display device to modify image(s) actually displayed, by changing the position or the size of the image(s) actually displayed, according to the operation parameter(s).

A screen recording method computes an encoding delay for each frame of a screen of an electronic device. The frame is encoded by a first compression algorithm if the encoding delay is short. The frame is encoded by an second compression algorithm if the encoding delay is middle and a time interval between the encoding time of a previous frame and the encoding time of a current frame does not exceed a first preset time interval. The frame is encoded by a third compression algorithm if the encoding delay is long and a time interval between the encoding time of a previous frame and the encoding time of a current frame exceeds a second preset time interval.

A method for searching related terms first calculates a direct relationship between every two of a plurality of query terms to obtain a direct related matrix, and calculates a related score between every two of the query terms to obtain a related score matrix. The method further calculates an indirect relationship between every two of the query terms according to the direct relationship and the related score, and determines indirect terms of each query term according to the indirect relationship between every two of the query terms.

A pixel unit including a first sub-pixel is disclosed. The first sub-pixel includes a first display medium, a second display medium, a first driving device, and a second driving device. The first driving device drives the first display medium. The second driving device drives the second display medium.

A method for accessing attribute data of virtual machines using a control computer. The method generates a control command for accessing the virtual machines of a host computer, determines a command type of the control command, obtains attribute data of a first type of the virtual machines from a database of the control computer if the command type is a first type and the control command is a data query command. The method transmits the control command to a virtual machine manager of the host computer if the command type is a second type, and receives attribute data of a second type of the virtual machines returned from the virtual machine manager of the host computer.

A method for filtering noise in an image filters noise pixels in a discrepant block between a current image and a background image firstly, and further filter each small block whose area is less than a preset value from the discrepant block. The method further calculates a total area of each big block whose area is greater than or equal to the preset value from the discrepant block, and adds the current image to a background list of the current image if the total area is less than another preset value.
摘要:
A processing digital noise method generates a matrix according to pixel values of pixels of a digital image, and selects a sub-matrix from the matrix. The sub-matrix has the same dimensions as a digital noise sample and includes a pixel value of a pixel selected from the digital image. The digital noise sample is represented as a matrix composed of 0 and 1. The method compares the sub-matrix with the digital noise sample to determine whether or not all values in the sub-matrix and the digital noise sample are the same. If all values are the same, the method further searches 1 from the sub-matrix for locating digital noise of the digital image, and removes the digital noise of the digital image by changing the pixel values of the digital noise from 1 to 0.

A method searches related terms using an electronic device. The method adds time stamps to one or more electronic documents, and obtains related terms according to the electronic documents. The method further calculates a time gap between each related term and a preset query term, obtains updated related terms by removing specified related terms whose time gap is greater than a preset value, and obtains search results from a data source by performing a search operation according to the updated related terms.
摘要:
An image comparison method compares a reference image with a test image. Each image includes objects and a background. The method generates a skeleton image of the reference image. The skeleton image of the reference image is compared with the test image so as to determine if the reference image have more objects or objects parts than the test image. Similarly, a skeleton image of the test image is generated. The skeleton image of the test image is compared with the reference image so as to determine if the test image have more objects or objects parts than the reference image.
