Abstract
A method includes obtaining, at a data reduction module, metrics of a first block of an input video frame and a second block of a reference frame. The data reduction module includes an analysis module and a filter. A perceptual importance of the first block of the input video frame is determined at the analysis module using the metrics. An entropy of the input video frame provided to an encoder is adjusted at the filter of the data reduction module based on the perceptual importance of the first block of the input video frame.
