International Classification:

H04N 7/32

US Classification:

37524012, 375E07243

Abstract:

A method of encoding a coding unit of a digital video sequence is provided that includes computing a brightness measure for each region in a plurality of regions in the coding unit, wherein the brightness measure indicates a relative brightness between the region in the coding unit and a corresponding region in a reference coding unit, determining a number of regions in the plurality of regions with significant brightness change by comparing each brightness measure to a region brightness change threshold, detecting whether there is global brightness change in the coding unit by comparing the number of regions to a global brightness threshold, and when global brightness change is detected, computing weighted prediction factors to be used for weighted prediction in encoding the coding unit.

International Classification:

H04N 7/32

US Classification:

37524016, 375E07243

Abstract:

A method and apparatus for determining a region-based weighted prediction with improved global brightness detection. The method includes applying a global brightness change detection methods by computing the weighted prediction parameters, determining if the brightness change is different amount of change for the different regions, if the change is not different, calculate motion estimation and setting Refidx to 1 and setting Refidx is set to 0 when there is change, determining the best motion vector, motion vector cost and the best reference input, and determining a region-based weighted prediction with improved global brightness detection based on the motion vector data.

Appl. No.:

13/438669

Inventors:

Hyung Joon Kim - McKinney TX, US

International Classification:

H04N 7/34

US Classification:

37524016, 375E07108

Abstract:

Iterative grid-pattern motion search may be performed for each macroblock of a frame of video data. A first motion search is performed from an initial best search point on a set of search points in the prior frame corresponding to a sub-set of pels within the macroblock to determine a best search point. Additional motion searches are performed iteratively, wherein each motion search is on a set of search points in the prior frame centered around a best search point determined in a preceding motion search. The motion vector for the macroblock is then estimated using a best search point determined in a final motion search iteration. A current best search point may be modified prior to performing an additional motion search by shifting to an adjacent search point in a direction indicated by the current best search point.
