SSIM: Structural similarity index (SSI) between two images.

In ANTsX/ANTsRNet: Neural Networks for Medical Image Processing

Structural similarity index (SSI) between two images.

Description

Implementation of the SSI quantity for two images proposed in

Usage

SSIM(x, y, K = c(0.01, 0.03))

Arguments

x	input image.
y	input image.
K	vector of length 2 which contain SSI parameters meant to stabilize the formula in case of weak denominators.

Value
