Summary:Evaluating coded video by identifying spatial and temporal errors in the reconstructed video. Spatial errors may be identified by evaluating the severity of each individual error and pooling closely located errors to determine whether the collection of errors is noticeable. Temporal errors may be identified by evaluating the quality of each frame and then pooling consecutive frames to determine whether the collection of frames has errors that may be noticeable if the errors persist within the sequence of consecutive frames. The quality of the frames may be analyzed with any conventional analysis metric. In an embodiment, the quality of the frames may be analyzed using a row-column metric. The calculated analysis metrics may be normalized to accurately compare different metric calculations.
