20090245694 | MOTION COMPENSATED TEMPORAL INTERPOLATION FOR FRAME RATE CONVERSION OF VIDEO SIGNALS - The present invention relates to a method for interpolating a subpixel at an interpolation position, which is situated in the chronological order between two source frames. Thereby the calculation of the interpolated subpixel's value is based on the value of the pixels of the two source frames and additional weighting coefficients, which are based on the motion vectors correlating the two source frames. | 10-01-2009 |
20110085737 | METHOD AND SYSTEM FOR DETECTING EDGES WITHIN AN IMAGE - The present invention relates to a method for detecting edges within an image. | 04-14-2011 |
20110235921 | METHOD AND APPARATUS FOR DETECTING CODING ARTIFACTS IN AN IMAGE - The present invention relates to a method and a corresponding apparatus for detecting coding artifacts in an image. The proposed apparatus comprises an edge position detector that detects an edge position of an edge in said image, a border position detector that detects a border position of a border between a texture area and a flat area in said image, and an artifact position defining unit that defines the area between said edge position and said border position as artifact area potentially comprising coding artifacts. | 09-29-2011 |
20120019667 | METHOD AND DEVICE FOR ADAPTIVE NOISE MEASUREMENT OF A VIDEO SIGNAL - The present invention relates to method of adaptive noise measurement of a video signal comprising a sequence of images. The proposed method comprises the steps of searching one or more spatially uniform areas within a current image, determining a spatial uniformity value of said one or more spatially uniform areas and combining said spatial uniformity values to obtain a spatial noise value representing a first measure for the amount of noise in said current image, detecting motion by comparing the current image with one or more preceding images and/or one or more succeeding images of said sequence of images by use of a motion threshold to obtain one or more motion maps indicating the amount of motion between the current image and the respective preceding or succeeding image, searching one or more static areas within said one or more motion maps, determining a temporal uniformity value for said one or more static areas by comparing image values at positions in said one or more preceding images and/or said one or more succeeding images, at which a low amount or no motion is indicated in the respective one or more motion maps, said temporal uniformity value representing a measure for the amount of noise at said positions in said current image, and combining said obtained temporal uniformity values to obtain a combined noise value representing a second measure for the amount of noise in said current image. | 01-26-2012 |
20120201390 | DEVICE AND METHOD FOR AUDIBLE TRANSIENT NOISE DETECTION - The present invention relates to a device and a corresponding method for audible transient noise detection in an audio signal. To avoid the detection of false positives or at least reduce the number of detected false positives a device is proposed comprising a detector configured to detect a set of transient noise candidates in time or frequency domain among a plurality of samples of said audio signal, and a selector configured to select audible transient noise candidates from said set of transient noise candidates by use of one or more selection criteria, wherein the selection criteria used for said selection are selected and/or whose parameters are at least partly set based on characteristics of said audio signal. | 08-09-2012 |
20150208005 | CAMERA SYSTEM, ESPECIALLY FOR A VEHICLE, AND METHOD FOR ASCERTAINING IMAGE INFORMATION OF A SIGNAL SOURCE PULSED AS A FUNCTION OF TIME - A camera system is described, particularly for a vehicle, the camera system having at least: a camera which has an image sensor and a filter mask, and a control and evaluation device which receives image signals output by the image sensor, the image sensor having an array of sensor pixels outputting pixel signals, and the filter mask having an array of filters which are disposed in front of the sensor pixels and have different wavelength-selective transmission response, a portion of the filters being attenuation filters, and sensor pixels, in front of which in each case one of the attenuation filters is disposed, outputting attenuation pixel signals. The attenuation filters advantageously attenuate white light more strongly than the other filters of the filter mask; in particular, they are blue pixels. | 07-23-2015 |
20150302262 | METHOD AND DEVICE FOR DETECTING VARIABLE MESSAGE TRAFFIC SIGNS - A method for detecting variable message traffic signs for a vehicle, includes: reading in a vehicle position, comparing the vehicle position to position information of at least one variable message traffic sign in order to determine a presence of a variable message traffic sign in a predefined area around the vehicle and in response to provide a proximity information, and varying a detection instruction of information of a variable message traffic sign in response to the proximity information to detect a variable message traffic sign. | 10-22-2015 |
