Description
A filter that compute an objective video quality metric between two videos. Based on SSIM work from Zhou Wang.
Requirements
Syntax and Parameters
- SSIM (clip, clip, string, string, int "lumimask", int "scaled")
- SSIM_FRAME (clip, clip)
- SSIM_Y_FRAME (clip, clip)
- SSIM_U_FRAME (clip, clip)
- SSIM_V_FRAME (clip, clip)
- clip =
- clip1 and clip2 are the reference clip and the compressed clip.
- clip =
- string = "results.csv"
- The file where obtained SSIM values will be written (this can be easily read in excel or notepad for those unfamiliar with the comma separated variables format)
- string = "results.csv"
- string = "globalSSIM.txt"
- The file where global SSIM values will be written.
- string = "globalSSIM.txt"
- int lumimask = 1
- This filter is designed to compute an SSIM value by three methods, the original one, and a "enhanced" one that weight these results by lumimasking.
- 0 : lumamasking disabled
- 1 : lumamasking enabled (original method)
- 2 : lumamasking enabled (new method as proposed by On2Tech) - see discussion here and here for more info.
- int lumimask = 1
- int scaled = 1
- The global score is scaled from 0 to 100 instead of 0 to 1. Set to false if you prefer it non-scaled.
- 0 : false
- 1 : true
- int scaled = 1
