However, the biggest clue appears when we apply a basic color histogram to the picture
Can anyone explain what this means? It doesn't match my understanding of what a histogram is (i.e., a graph of values vs frequency of occurrence).
- ronaldx 13y agoI can't see the images in the article but you have it right - the histogram is color values against frequency. You can then use the histogram to identify and highlight particular color values in the image. This would identify the simple artefact described in the text.
