Landscape More Secure Than Portrait? Zooming Into the Directionality of Digital Images With Security Implications

arXiv:2406.15206v1 Announce Type: cross
Abstract: The orientation in which a source image is captured can affect the resulting security in downstream applications. One reason for this is that many state-of-the-art methods in media security assume that image statistics are similar in the horizontal and vertical directions, allowing them to reduce the number of features (or trainable weights) by merging coefficients. We show that this artificial symmetrization tends to suppress important properties of natural images and common processing operations, causing a …
