How do you account for temporal and spatial alignment between clips in the PQA500?

問題:

How do you account for temporal and spatial alignment between clips in the PQA500?

答案:

The PQA500 supports both manual and automatic alignment of reference and test clips by adjusting the following items:

1)     Temporal Sync:

  • Start and end frame or time for reference clip
  • Start and end frame or time for test clip
  • Temporal offset (shift) between reference and test clips
  • Test clip frame rate

01

2)     Spatial Alignment:

  • Horizontal and/or vertical shift between reference and test clips
  • Horizontal and/or vertical scaling or stretching between reference and test clips
  • Horizontal and/or vertical cropping between reference and test clips (letterboxing, zoom etc...)
  • Overall luminance gain and/or DC offset between reference and test clips

02

The user is given a choice of either manually adjusting each of these parameters while they watch a live-running PSNR until they achieve temporal and spatial alignment between the clips or if they wish they can run an automatic alignment which will scan a portion of the video clips looking for similarities and automatically determine the best temporal and spatial alignment.
