Title:
フレーム系列の歪んだバージョンの品質を評価する方法
Document Type and Number:
Japanese Patent JP5721936
Kind Code:
B2
Abstract:
The invention is related to a method for assessing the quality of a distorted version of a frame sequence. Said method comprises the steps of determining a last spatial distortion by comparing a block (B6) of a last frame (16) of the sequence with a corresponding block of the distorted version of the last frame, determining, in a last-but-one frame (I5), a best-matching block (B5) matching said block (B6) of the last frame (16) best, determining a last-but-one spatial distortion by comparing the determined best-matching block (B5) of the last-but-one frame (I5) with a corresponding block of the distorted version of the last-but-one frame and determining a spatio-temporal perceptual distortion (STPDM) of the distorted version of the frame sequence using the determined distortions. By taking the temporal evolution of the spatial distortion associated with a block into account, the quality of the distorted video is assessed better.
