  • Patent number: 7949205
    Abstract: An image processing unit for computing a sequence of output images on basis of a sequence of input images, comprises: a motion estimation unit for computing a motion vector field on basis of the input images; a quality measurement unit for computing a value of a quality measure for the motion vector field; an interpolation unit for computing the output images by means of interpolation of pixel values of the input images, on basis of the motion vector field; and control means to control the interpolation unit on basis of the quality measure. The quality measurement unit is arranged to compute the value of the quality measure on basis of a maximum difference between neighboring motion vectors. If the value of the quality measure is lower than a predetermined threshold, then a motion compensated interpolation is performed, else a non-motion compensated interpolation is performed.

  • Patent number: 7519230
    Abstract: A selector (502) for selecting a background motion vector for a pixel in an occlusion region of an image, from a set of motion vectors being computed for the image, comprises: computing means (510) for computing a model-based motion vector for the pixel on basis of a motion model being determined on basis of a part of (402-436) a motion vector field (400) of the image; comparing means (511) for comparing the model-based motion vector with each of the motion vectors of the set of motion vectors; and selecting means (512) for selecting a particular motion vector of the set of motion vectors on basis of the comparing and for assigning the particular motion vector as the background motion vector.

  • Patent number: 6937655
    Abstract: A method and arrangement for detecting a picture repetition mode of film material with a series of consecutive fields, the arrangement having a processor and a memory (M), the processor identifying a plurality of different objects within the consecutive fields using a segmentation method, an object being defined as an image portion of the consecutive fields that can be described with a single motion model; and carrying out the following steps for each one of the plurality of objects, i.e., establishing a motion parameter pattern for each one of the objects within the consecutive fields; comparing the motion parameter pattern with a number of predetermined motion parameter patterns; and determining the picture repetition mode for each one of the objects using the result of the preceding step.
