Abstract:
1. A method carried out by an electronic data processor, comprising: receiving target image data; applying a multiple stage filtering to the target image data, wherein each stage includes a filtering process comprising: spatially filtering the target image to produce a first prediction of the target image; using the first prediction to determine a first prediction error; applying a candidate pattern of motion vectors and a spatial-temporal filter to the target image to produce a second prediction of the target image; using the second prediction to determine a second prediction error; and using the candidate pattern of motion vectors as a motion vector sampling pattern if a difference between the first and second prediction errors is within a predetermined limit; using the target image data and the motion vector sampling pattern to generate a temporal prediction of the target image data; and using the temporal prediction of the target image data to generate a spatial-temporal transformation of the target image data.
