| 20080273806 | METHOD AND SYSTEM FOR INITIALIZING TEMPLATES OF MOVING OBJECTS - A method for tracking a moving object in a sequence of images is provided, comprising: partitioning each of said images of said sequence into blocks, identifying blocks which have moved between consecutive images of said sequence, grouping adjacent blocks, which have moved in a same direction by a same distance, into a first group of blocks, initializing an initial template for said moving object with said first group of blocks and tracking said template in said sequence of images. A corresponding system for tracking moving objects is presented as well. | 11-06-2008 |
| 20080309516 | METHOD FOR DETECTING MOVING OBJECTS IN A BLIND SPOT REGION OF A VEHICLE AND BLIND SPOT DETECTION DEVICE - A method for detecting moving objects In a blind spot of vehicle is provided, comprising: taking a sequence of images of said blind spot region, partitioning each of said images of said sequence into blocks, identifying moving blocks which have moved between consecutive images of said sequence, determining a direction and a distance of said movement of said moving blocks; grouping adjacent moving blocks, for which directions within a predetermined direction interval and distances within a predetermined distance interval have been determined, and determining said moving objects based on said step of grouping. A corresponding blind spot detection device is provided as well. | 12-18-2008 |
| 20090097542 | SIGNAL CODING AND DECODING WITH PRE- AND POST-PROCESSING - In a data compression, a pre-processing is applied to a signal before it is encoded and a post-processing is applied to a signal after it is decoded. A pre-processor for signals to be encoded includes a filtering device for filtering a signal with one or more filters and a providing device for providing information about the filtering process. A post-processor for previously filtered, encoded and decoded signals includes an information retrieving device for retrieving information about the filtering process and an inverse filtering device for inverse filtering the decoded signal based on the retrieved information. | 04-16-2009 |

| 20100118956 | METHOD AND DEVICE FOR EXTRACTING A MEAN LUMINANCE VARIANCE FROM A SEQUENCE OF VIDEO FRAMES - A method and a device for extracting a mean luminance value from a inter-coded frame is proposed, wherein the inter-coded frame is a part of a sequence of video frames, the method comprising: approximating DC coefficients for macro-blocks of the inter-coded frame based on DC coefficients of intra-coded macro-blocks surrounding reference blocks in a reference frame of the sequence, the reference blocks being pointed to by motion vectors of the macro-blocks of the inter-coded frame; and calculating the mean luminance value based on the approximated DC coefficients. | 05-13-2010 |
| 20100158122 | METHOD AND DEVICE FOR APPROXIMATING A DC COEFFICIENT OF A BLOCK OF PIXELS OF A FRAME - A method and a device for approximating a DC coefficient of a first block of pixels of a first frame are proposed. The method comprises: calculating a luminance DC average value based on DC coefficients of first frame's macro-blocks without an approximation error; and determining the DC coefficient of the first block based on the DC coefficient of a second block, wherein the second block is a part of a second frame, which is a reference frame of the first frame, the second block overlapping with a reference block of the first block and having the closest DC coefficient to the luminance DC average value. | 06-24-2010 |
| 20100245613 | METHOD AND UNIT FOR GENERATING HIGH DYNAMIC RANGE IMAGE AND VIDEO FRAME - An embodiment of the invention relates to a method for High Dynamic Range (HDR) image creation by generating a mean difference curve for use in aligning the images of a sequence of images taken with different exposures, wherein the difference in exposure might derive from a difference in exposure time or a difference in aperture size. A further embodiment of the invention relates to a method for HDR image creation by generating images with different exposures from a single image. A further embodiment of the invention relates to a method for HDR video creation by generating frames with different exposures from a single frame. | 09-30-2010 |
| 20110050920 | METHOD, SYSTEM AND COMPUTER PROGRAM PRODUCT FOR REDUCING MOTION BLUR - The present invention relates to a method for reducing motion blur. According to the method, at least two image frames are captured. A sequence of values is provided. All captured frames are processed by subsequently associating one sequence value with each captured frame. The processed captured frames are accumulated and a deconvolution is applied to the accumulated frame. | 03-03-2011 |
| 20110085743 | METHOD AND SYSTEM FOR REDUCING RINGING ARTIFACTS OF IMAGE DECONVOLUTION - The present invention relates to a method for reducing ringing artifacts of image deconvolution. A deconvolution is applied to the original blurred image and edges are detected within the deconvolved image. Then edge tapering on the original blurred image is performed based on the detected edges. | 04-14-2011 |
