20100232509 | METHOD AND APPARATUS TO IMPROVE THE CONVERGENCE SPEED OF A RECURSIVE MOTION ESTIMATOR - A method and apparatus for motion estimation of at least a first and a second image frame by estimating at least one motion vector correlating a portion of pixels of the at least first and second image frame, the first and second image frame being part of an image frame sequence. The at least one motion vector is obtained by a predominant motion detection generating at least one global motion vector based on at least one previously determined motion vector, the previously determined motion vector correlating a portion of pixels of earlier image frames of the image frame sequence, and an estimation estimating the at least one motion vector based on the at least one global motion vector. | 09-16-2010 |
20140043447 | CALIBRATION IN THE LOOP - Method for iteratively calibrating a disparity estimation process generating a disparity estimation map relating to a 3D image which consists of at least a right and a left image, the method comprising: estimating a left-to-right image disparity map of a 3D image in horizontal and vertical direction, estimating a right-to-left image disparity map of the 3D image in horizontal and vertical direction, determining a misalignment value between the left and right images on the basis of the disparity maps, feeding back the misalignment value as to be considered in the next estimating the disparity maps of a next 3D image, and repeating the method for the next 3D image to iteratively calibrate the disparity estimation process. | 02-13-2014 |
20140198852 | METHOD FOR STABILIZING A FIRST SEQUENCE OF DIGITAL IMAGE FRAMES AND IMAGE STABILIZATION UNIT - A method for stabilizing a first sequence of digital image frames is provided including determining a dominant motion vector of a dominant motion layer of said sequence; determining a first part of the dominant motion vector representative of an intended motion in said sequence; determining a second part of the dominant motion vector representative of an unintended motion in said sequence; and generating a second sequence from the first sequence based on the second part. A corresponding image stabilization unit is provided as well. | 07-17-2014 |
20140333720 | SUBTITLE DETECTION FOR STEREOSCOPIC VIDEO CONTENTS - A right image and a left image is provided. Then a disparity estimation map relating to both images is provided and a left subtitle detection map for the left image and a right subtitle detection map for the right image are generated. Each map indicates subtitle areas within an image. For said subtitle areas and based on said disparity estimation map a subtitle disparity value for X and Y directions common for all subtitle areas is determined. Said left and right subtitle maps and said subtitle X and Y disparity values are used in an image interpolation process. | 11-13-2014 |
