Dissertations / Theses: ''Re-sampling'' – Grafiati

However, the latter is superior in the less dimensionality of input vectors to the FLD classifier being used. Re-sizing an image is a typical example of re-sampling. In the third part of the thesis, we investigate the forensic detection of re-sampling for images. A new method is proposed to detect re-sampled imagery.
