摘要： In for example the assignment of motion vectors, an array of pixel-to-pixel dissimilarity values is analysed to identify a pixel which has a low pixel-to-pixel dissimilarity value and which has neighbouring pixels which have a low pixel-to-pixel dissimilarity value. The pixel-to-pixel dissimilarity values are filtered with a filter aperture decomposed into two or more sectors with partial filters applied respectively to each sector. Outputs of the partial filters are combining by a non-linear operation, for example taking the minimum from diametrically opposed sectors.

摘要： An array of pixel-to-pixel dissimilarity values is analysed to select a pixel which has a low pixel-to-pixel dissimilarity value and which has neighbouring pixels which have a low pixel-to-pixel dissimilarity value. Each pixel-to-pixel dissimilarity value represents a difference between the value of a pixel in a first spatial pixel array representing a first image and the value of a corresponding pixel in a second spatial pixel array representing a second image. The pixels neighbouring the current pixel are divided into at least two polar sectors. The current pixel is selected when the current pixel and the pixels of at least one polar sector have low dissimilarity values.

摘要： An image or other sample processor has a resampling filter adapted to provide output samples at an output sampling frequency which can be selected to be higher or lower than the input sampling frequency. The width of the resampling filter aperture is scaled according to either the input sampling frequency or the output sampling frequency so as to obtain the wider of the two possible filter apertures.

摘要： In video motion estimation an initial candidate motion vector is generated for each block and a vector error is determined as for example a DFD. Spatial gradients of pixel values are calculated and used to refine the initial candidate motion vector. The relative contribution of the spatial gradients to the refinement process depends on the vector error.
