Description

A filter that compute an objective video quality metric between two videos. Based on SSIM work from Zhou Wang.

Requirements

• AviSynth 2.6 or greater | AviSynth+
• x64 requires x64 AviSynth+
• Supported color formats: YV12

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.

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   = "globalSSIM.txt"

The file where global SSIM values will be written.

int  lumimask = 1

This filter is designed to compute an SSIM value by two methods, the original one, and a "enhanced" one that weight these results by lumimasking (true).

0 : false

1 : true

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
