utilizing an error function biased towards spatio-temporal
consistency with a penalty function. The penalty function
increases with the spatial and temporal distance of the subject
block from the block for which the candidate vector was optimal.
Claim 1 is illustrative of the invention and reads as
follows:
1. A receiver, including a video enhancement
mechanism for enhancing video information with spatio-
temporal consistency, comprising:
at least one enhancement unit enhancing a
characteristic other than position of a selected pixel
region of video information utilizing at least one candidate
enhancement vector of enhancement algorithms to generate an
enhanced pixel region for each candidate enhancement vector,
each said enhanced pixel region equivalent to enhancement of
said selected pixel region utilizing a respective candidate
enhancement vector of enhancement algorithms; and
a selection unit computing an error for each said
enhanced pixel region utilizing a bias towards spatio-
temporal consistency of a respective enhanced pixel region
with spatially adjacent pixel regions in a picture
containing said selected pixel region and with a counterpart
pixel region in one or more pictures successive with said
picture containing said selected pixel region, said
selection unit selecting an enhanced pixel region having a
best enhancement for spatio-temporal consistency.
