Abstract

An apparatus for image pair analysis according to an embodiment is provided. The apparatus comprises a metrics determiner (110) for determining three or more metrics for each image pair of a plurality of image pairs. Each of the three or more metrics indicates a metric for a difference between two images of the image pair. Moreover, the apparatus comprises a dimensionality reducer (120) for conducting a dimensionality reduction to obtain two or more principal components depending on the three or more metrics for each image pair of the plurality of image pairs. Furthermore, the apparatus comprises a clustering module (130) for clustering the plurality of image pairs into two or more clusters by assigning each of the plurality of image pairs to one of the two or more clusters depending on the two or more principal components of each of the plurality of image pairs. Moreover the apparatus comprises an output interface (140) for outputting information on the clustering of the plurality of image pairs or for outputting information that depends on the clustering of the plurality of image pairs.
