A system and method for detecting a particular human in a plurality of images of humans may include one or more processors to receive input data describing the appearance of the particular human via a graphical user interface (GUI). An image representing the particular human may be generated based on the input data. This may take the form of an avatar or artificial image. This artificial or processor-generated image may be used to identify one or more of the humans in said plurality of images as a candidate for the particular human.
