evaluate-similarity

Synopsis

evaluate-similarity <target> <source>... [options]

Description

Evaluates the (dis-)similarity of two intensity images.

If more than one source image is given, the (dis-)similarity between each of these and the target is evaluated. By default, common image (dis-)similarity metrics are reported. One or more metrics for the evaluation can be chosen using evaluate-similarity -metric.

The input source image can either be pre-aligned with the target image or the output of a previous registration can be specified using evaluate-similarity -dofin.

Arguments

target

Target image.

source

Source image.

Command options
