Abstract
An AZB detection method for video coding, which includes the steps of detecting if a residual signal includes a spatial domain GAZB; detecting if the residual signal includes a frequency domain GAZB if no spatial domain GAZB is detected in the previous step; detecting if the residual signal includes a PAZB if no frequency domain GAZB is detected in the previous step; and determining that the residual signal is a non-AZB signal if no PAZB is detected in the previous step. The proposed method achieves promising time savings for test sequences of different resolutions, with negligible rate-distortion performance loss.
