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 |
20090273709 | METHOD FOR CONVERTING AN IMAGE AND IMAGE CONVERSION UNIT - A method for converting an image and an image conversion unit are provided, the method comprising: determining a target pixel of pixels of the image; calculating a first value based on pixel values of a first set of pixels, wherein the first set of pixels do not include pixels in a column of the target pixel; determining a second value based on pixel values of a second set of pixels, wherein the second set of pixels are located in the column of the target pixel; and determining a pixel value of the target pixel based on adding the first and second values. The method and the image conversion unit are used e.g. for converting an image in interlaced format to progressive scan format. | 11-05-2009 |
20100091126 | METHOD AND UNIT FOR MOTION DETECTION BASED ON A DIFFERENCE HISTOGRAM - Method for motion detection in a current picture (CP) with respect to a reference picture (RP), wherein for a plurality of locations in the current picture (CP) respective difference values (|D|) are determined (B | 04-15-2010 |
20100091194 | NOISE REDUCTION METHOD AND UNIT FOR AN IMAGE FRAME - A method and unit for noise reduction in a current image frame, wherein the current image frame is a part of a sequence of image frames. The method compares a current pixel value of a pixel within the current image frame with a corresponding pixel value of the pixel in at least one adjacent image frame, and determines a piled-up value of the current pixel value and the corresponding pixel value if a pixel difference between the current pixel value and the corresponding pixel value is below a pixel threshold, wherein the pixel threshold depends on the corresponding pixel value and/or the current pixel value. The method and unit can be applied for block and color processing as well. | 04-15-2010 |
20110060976 | METHOD AND DEVICE FOR PROCESSING SIGNAL DATA - A method of processing signal data comprises receiving signal data, calculating a first k-th moment from the signal data based on a first number of samples N | 03-10-2011 |
20110228981 | METHOD AND SYSTEM FOR PROCESSING IMAGE DATA - A method for processing image data representing a segmentation mask, comprises generating two-dimensional shape representations of a three-dimensional object on the basis of a plurality of parameter sets; and matching motion blocks of the segmentation mask with the two-dimensional shape representations to obtain a best fit parameter set. Thereby, for example, a distance between the three-dimensional object and a camera position may be determined. | 09-22-2011 |

20130278726 | IMAGING SYSTEM USING A LENS UNIT WITH LONGITUDINAL CHROMATIC ABERRATIONS AND METHOD OF OPERATING - A lens unit of an imaging unit features longitudinal chromatic aberration. From an imaged scene, an imaging sensor unit captures non-color-corrected first images of different spectral content. An intensity processing unit computes broadband luminance sharpness information from the first images on the basis of information descriptive for imaging properties of the lens unit. A chrominance processing unit computes chrominance information on the basis of the first images. A synthesizing unit combines the computed chrominance and luminance information to provide an output image having, for example, extended depth-of-field. The imaging unit may be provided in a camera system, a digital microscope, as examples. | 10-24-2013 |
