Abstract: Various embodiments are generally directed to techniques for evaluating the resulting image quality of compression of motion videos as an input to controlling the degree of compression. A device to compress motion video includes a compressor to compress a first uncompressed frame of a motion video to generate a first compressed frame of the motion video for a viewing device having at least one viewing characteristic, and a mean opinion score (MOS) estimator to combine a structural metric of image quality of the first compressed frame and an opinion metric of image quality associated with the at least one viewing characteristic to determine whether to alter a quantization parameter (QP) of the compressor to compress a second uncompressed frame of the motion video. Other embodiments are described and claimed.

Abstract: Various embodiments are generally directed to techniques for evaluating video quality of compressed versions of a motion video to select compressed frames of that motion video without access to an uncompressed version. A device to transmit motion video includes a device scoring component to select a set of coefficients from a vector correlating temporal complexity values to sets of coefficients based on a temporal complexity of a first compressed frame of a first compressed video data, the vector derived from opinion scores associated with at least one viewing characteristic of a viewing device; and a selection component to select either the first compressed frame or a second compressed frame of a second compressed data to transmit to the viewing device based on a metric of video quality derived from the selected set of coefficients, the first and second compressed data representing a motion video. Other embodiments are described and claimed.
