Abstract:
The present specification relates to an apparatus for generating an electronic warfare threat library based on a threat detection path and a search bandwidth and a method thereof, which generate information on a mission plan including the threat detection path and an automated search bandwidth generation function and generate the warfare threat library based on the generated information on the mission plan. For this, the method for generating the warfare threat library based on the information on the mission plan including the threat detection path and the search bandwidth for an arbitrary mission comprises the steps of: when a preset button or application program is selected, displaying a list of information on the mission plans including information relating to the information on the plural mission plans; and, when the information on at least one mission plan among the displayed list of the information on the mission plans, generating the threat library based on the information on the at least one mission plan prestored at a mission plan information database corresponding to the information on the selected at least one mission plan.
Abstract:
PURPOSE: An image manipulation detection method and a device thereof are provided to detect whether a target image, which is examined, is manipulated or not by extracting Photo Response Non-Uniformity (PRNU) from the target image and extracting a correlation plane based on the extracted value. CONSTITUTION: An image manipulation detection device calculates the change rate of the size of a target image which is examined and restores the target image (S210). The image manipulation detection device extracts Photo Response Non-Uniformity (PRNU) from the target image (S220). The image manipulation detection device calculates Peak to Correlation Energy (PCE) using a correlation plane which is obtained by comparing the extracted PRNU and standard PRNU (S230, S240). The image manipulation detection device determines whether the device which photographed the target image is a standard device or not by comparing the calculated PCE and the standard PCE of the standard device (S250). [Reference numerals] (S210) Calculate the change rate of a target image and restore the target image for the size of a target image to respond to the calculated the change rate of size; (S220) Extract Photo Response Non-Uniformity (PRNU) from the target image; (S230) Use the PRNU value of the standard device to compare the similarity between the extracted PRNU value and the standard PRNU value; (S240) Calculate PCE value by using correlation section calculate through the comparison result; (S250) Determine whether the device which photographed the target image is a standard device or not by comparing the calculated PCE and the standard PCE of the standard device
Abstract:
PURPOSE: An image identification device and a method thereof are provided to sense re-photographed illegal copyright infringement images uploaded on the Internet by discriminating whether an image is re-photographed on the basis of shot-based PRNU(Photo Response Non Uniformity) included in the image. CONSTITUTION: An image acquisition unit(120) acquires input images. A control unit(110) classifies the input image into shots which have at least one frame, detects PRNU corresponding to the shots, and judges whether the input image is a re-photographed image on the basis of the detected PRNU. A memory unit(130) stores information processed in an image identification device(100). [Reference numerals] (110) Control unit; (120) Image acquisition unit; (130) Memory unit
