title = "Investigation of the effects on embedded watermarks under image manipulations",
abstract = "In this paper, different types of image watermarking techniques, the embedding of data or copyright information into the data file, are investigated. Three image watermarking techniques are discussed, namely: least significant bit, least significant bit and discrete cosine transform combined, and discrete cosine transform and discrete wavelet transform combined. These embedded watermarking techniques are evaluated on how robust each technique is under image manipulations. Simulations are done using the three image watermarking techniques to determine the effects on how well the embedded watermarking technique resists manipulations. Different watermarking techniques resulted in high robustness in some cases but showed visible artefacts, in other cases robustness was low but image quality stayed relatively close to the original watermark.",
