Digital Image Forensic - Image Forensics: Modified

Modification detection

 

Altered or manipulated - always a problem?

Often digital images are altered with the help of image editing software. Minor adjustments necessary for accurate reproduction are very common. Those are cropping, conversion into greyscale and maybe tonal or color corrections.

Basically, image-alteration detection is a question of yes/no. Still it depends from country to country if alteration is a serious violation of the code of ethics or not.
