Metric behavior for (a) inter-individual errors within the “measured” dataset (with IDs 13, 8, 1 as reference, from left to right) and for intra-individual errors between (b) the “measured” and “anthroPCA”, (c) the “measured” and “idealPCA”, and (d) the “idealPCA” and “anthroPCA” datasets. The box plots (top) visualize the distribution of metric values, normalized by the 95th percentile of each metric. Two example pairs of transfer functions are depicted in the middle row, with an offset of 20 dB introduced for better visibility. Corresponding (normalized) metric values are indicated by the gray and black lines superimposing the box plots. Pearson correlation coefficients with p < 0.05 after Bonferroni correction (bottom) display varying patterns, with most prominent differences present in case (c).

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
