摘要： 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.

摘要： Image data processing is facilitated. According to an example embodiment, image data is processed using photometric similarity and, where appropriate, a classification of sample pixels for the image data. In some applications, a trained bilateral filter function is used with a filter coefficient selected for a particular classification of image data to filter artifacts in the image data.

摘要： The invention relates to a method and a circuit arrangement to reduce motion blur of images shown in non-stroboscopic display devices, in particular Liquid Crystal Display Panels (LCDs). Thin Film Transistor Displays (TFTs), Color Sequential Displays. Plasma Display Panels (PDPs), Digital Micro Mirror Devices or Organic Light-Emitting Diode (OLED) displays, in which motion vectors depending on moving components in each image of an input video, signal are calculated, in which anti-motion blur filtering of the input video signal is performed based on the calculated motion vectors to produce an output video signal, and in which images are generated on said display device depending on said output video signal. In order to provide an improved spatial filtering with less noise enhancement and less noise modulation, it is proposed that edge characteristics in each image of the input video signal are determined and that anti-motion blur filtering is further based on said determined edge characteristics. In this way, spatial filtering is concentrated on significant parts of an image only, and both noise enhancement and noise modulation are reduced.

摘要： This invention relates to a method for image enhancement, comprising a first step (41) of distinguishing blurred and non-blurred image portions of an input image, and a second step (42) of enhancing at least one of said blurred image portions of said input image to produce an output image. Said blurred and non-blurred image portions are for instance distinguished by comparing (416) the differences (415) between a linearly up-scaled (414) version of the down-scaled (411) input image and the input image, and the differences (413) between a non-linearly up-scaled (412) representation of the down-scaled input image and the input image. Said blurred image portion is for instance enhanced by replacing (42) it with a portion of a non-linearly up-scaled representation of the down-scaled input image. The invention also relates to a device, a computer program, and a computer program product.
