Sometimes cutting out the face of people leads to more search results on Google image search. Perhaps this is due to the search engine tending to be way more biased when faces appear in images such that the internally generated search is too specific. Sometimes, images with faces lead to no search results at all compared to an image with a cut-out face.

The following image is an excerpt from a TV show and it is an image based on an older Internet meme, dating back to Slackware (during troublesome years), that the TV show hosts modified by flipping the image horizontally and then swapping the face for someone else. Here is the original image extracted from the TV show.

Searching for the original image yields no search results such that first cutting out the face and searching again produces way more results, as well as finding the original image that was modified by the TV show.

More than likely the Google search engine along with image detection technology heavily contextualizes faces such that the filters end up over-impressed by the face rather than the rest of what the image shows, such as the lake, the boat and the life-vest.
