Abstract
In one embodiment, a method including dividing a reference mask into a plurality of reference mask divisions, determining a plurality of motion vectors respectively associated with a plurality of slice divisions, wherein the plurality of reference mask divisions respectively correspond to the plurality of slice divisions, modifying a blurring kernel in accordance with the plurality of motion vectors, yielding a plurality of modified blurring kernels that are respectively associated with the plurality of slice divisions, and performing at least one action to yield an altered reference mask, including for the plurality of reference mask divisions and the plurality of modified blurring kernels: convolving a reference mask division with a weighted function of at least a modified blurring kernel associated with a slice division, of the plurality of slice divisions, to which the reference mask division corresponds.
