A method and system for automated video quality assessment which reduces the adverse effects of sub-field/frame misalignments between the reference and test sequences. More particularly, the invention provides for misalignments down to a sub-field/frame level to be handled by individually matching sub-field/frame elements of a test video field/frame with sub-field/frame elements from a reference video field/frame. The use of a matching element size that is significantly smaller than the video field/frame size enables transient sub-field/frame misalignments to be effectively tracked.

Method and system for video quality assessment

The quality of audiovisual material is assessed by measuring the audio an video quality and computing from these a combined measure. Using a parameter indicative of the degree of motion represented by the video, the computation employs one of a plurality of algorithms selected in dependence on the value of the parameter.
