摘要: The invention relates to an interpolating filter with coefficients that depend on the motion vector value, which uses samples that exist in the current field and additional samples from a neighboring field shifted over a part of a motion vector. Using samples from the current field and the motion compensated previous field that are not for vectors on a vertical line, the robustness of the de-interlacing may be increased. The interpolation quality may be better without increasing the number of input pixels.

摘要: The invention relates to a method for de-interlacing a hybrid video sequence using at least one estimated motion vector for interpolating pixels. Field for petition patents, typically occurring in film originated video material, disturb the function of de-interlacing algorithm designed to convert interlaced video single into progressively scanned video. Therefore a mode decision has to be applied for local adaptation to the film/video mode, which is possible by defining values for a first motion vector and a second motion vector, calculating at least one first pixel using at least one pixel of previous image and one first motion vector, calculating at least one second pixel using at least one pixel of a next image and one second motion vector, calculating a reliability of said first and the second motion vector by comparing at least said first pixel with at least said second pixel the first and said second motion vectors being pre-defined for said calculation of reliability, and estimation an actual value for a motion vector, which turned out to be most reliable for de-interlacing said image.

摘要: The invention relates to a method for providing a motion parameter set and/or a picture repetition pattern from an input video signal, in particular for de-interlacing a video signal with using a candidate motion parameter set weighted with a picture repetition pattern value for calculating a motion compensated pixel from a pixel value of a first image. To provide motion compensation which accounts for field repetition patterns, minimizing an error criterion between at least one pixel value of a second image and at least the motion compensated pixel value by iterating the calculation of the motion compensated pixel with at least two candidate motion parameters sets and/or at least two picture repetition values, and putting out the candidate motion parameter set and/or the picture repetition value which provides the minimized error criterion is proposed.

摘要: The invention relates to a method, a device, and a computer programme product for calculating a motion vector from an interlaced video signal with interpolating a first pixel sample from a first set of pixels and a second set of pixels using a first motion vector, and interpolating a second pixel sample from the first set of pixels and a third set of pixels using a second motion vector. To improve motion estimation and de-interlacing, the invention provides interpolating pixels of the first set of pixels to calculate a third pixel sample as an average of at least two pixels within the first set of pixels, calculating a first relation between the first pixel sample and the third pixel sample, calculating a second relation between the second pixel sample and the third pixel sample, and selecting an output motion vector from a set of motion vectors by minimising the first and second r elation using the set of motion vectors.
