This invention concerns the interpolation of new intermediate images within an existing set of related images, for example views of a scene captured at different times, such as a sequence of film frames or video fields, or views of a scene captured from different camera positions, either simultaneously or in a time sequence. Motion vectors established for pixels or regions in at least one existing image are used to shift those pixels or regions to the output position of the new image. The shifted pixels or regions are combined in dependence on a probability of accuracy measure for the respective motion vector. The probability of accuracy measure may be formed from displaced-field difference measurements. The occlusion of objects is determined and used in forming the probability of accuracy measure.
A method of interpolating a new image within an existing sequence of related images using motion vectors applicable to pixels of an image in the said existing sequence, where the pixels of at least one existing image adjacent to the new image contribute to the new image, and the positions of the said contributions in the new image depend on scaled motion vectors applicable to respective contributing pixels, characterised in that:
A method of interpolating a new image at an output position within an existing sequence of related images, comprising the steps of:
A method of interpolating a new image within an existing sequence of images using motion vectors derived from comparison between existing images in the sequence wherein pixels of the new image are formed from weighted combinations of pixels from existing images in the sequence wherein one or more contributions from an existing image is reduced so as to account for the occlusion of objects portrayed in the new image, the said reduction depending on at least one comparison between existing images in the sequence.
