A single-ended blur detection probe and method with a local sharpness map for analyzing a video image sequence uses two sets of edge filters, one for “fast edges” and the other for “slow edges.” Each set of edge filters includes a horizontal bandpass filter, a vertical bandpass filter and a pair of orthogonal diagonal filters where the frequency response of the fast edge filters overlap the frequency response of the slow edge filters. The video image sequence is input to each filter of each set, and the output absolute values are combined with weighting factors to produce a slow edge weighted sum array and a fast edge weighted sum arra. The respective weighted sum arrays are then decimated to produce a slow edge decimated array and a fast edge decimated array. The ratio of the maximum difference value between the decimated arrays and the maximum value from the fast edge decimated array, weighted by an appropriate factor, produces a localized maximum sharpness value, the log of which produces a dimensionless blur value.

The video encoders described herein may make an initial determination to designate a macroblock as a skip macroblock, but may subsequently reverse that decision based on additional information. For example, an initial skip mode decision may be based on aggregate distortion metrics for the luma component of the macroblock (e.g., SAD, SATD, or SSD), then reversed based on an individual pixel difference metric, an aggregate or individual pixel metric for a chroma component of the macroblock, or on the position of the macroblock within a macroblock row. The final skip mode decision may be based, at least in part, on the maximum difference between any pixel in the macroblock (or in a region of interest within the macroblock) and the corresponding pixel in a reference frame. The initial skip mode decision may be made during an early stage of a pipelined video encoding process and reversed in a later stage.
