cutcutcodec.core.analysis.video.quality.vif

cutcutcodec.core.analysis.video.quality.vif(dis: Tensor, ref: Tensor) → Tensor

Compute the visual information fidelity of 2 images.

Parameters

dis, refarraylike

The 2 images to be compared, of shape ([*batch], height, width, channels=[1, 3]). The frames are assumed to be in Y or YUV (y’pbpr) in range [0, 1]. Only the y’ component is used.

Returns

vifarraylike

The visual information fidelity of each image.

Notes

This metric isn’t symmetric, so make sure to place arguments in correct order.
