skvideo.measure.mse¶

skvideo.measure.mse(referenceVideoData, distortedVideoData)[source]¶

Computes mean-squared error (MSE).

Both video inputs are compared frame-by-frame to obtain T MSE measurements.

Parameters:

referenceVideoDatandarray

Reference video, ndarray of dimension (T, M, N, C), (T, M, N), (M, N, C), or (M, N), where T is the number of frames, M is the height, N is width, and C is number of channels.

distortedVideoDatandarray

Distorted video, ndarray of dimension (T, M, N, C), (T, M, N), (M, N, C), or (M, N), where T is the number of frames, M is the height, N is width, and C is number of channels.

Returns:

mse_arrayndarray

The mse results, ndarray of dimension (T,), where T is the number of frames
