Most current steganographic schemes embed the secret payload by minimizing a
heuristically defined distortion. Similarly, their security is evaluated empirically using …

To ensure safety in the construction of important metallic components for roadworthiness, it
is necessary to check every component thoroughly using non-destructive testing. In last …

Since Röntgen discovered in 1895 [90] that X-rays can be used to identify inner structures, X-
rays have been developed not only for their use in medical imaging for human beings, but …

Castings produced for the automotive industry are considered important components for
overall roadworthiness. To ensure the safety of construction, it is necessary to check every …

The vast majority of steganographic schemes for digital images stored in the raster format
limit the amplitude of embedding changes to the smallest possible value. In this paper, we …

In the automotive industry, light-alloy aluminum castings are an important element for
determining roadworthiness. X-ray testing with computer vision is used during automated …

Recognizing defects in X-ray images plays an important role in the detection of internal
