Facial recognition appears in daily life frequently. Without the ability to recognize faces, life would be a confusing turmoil. From their birth, infants obtain rudimentary capabilities to process facial expressions. Infants are capable of mimicking expressions and have the aptitude to note details, such as eye and mouth shape. Many times, a graphic representation of an eyewitness’s memory of a face is used to solve crime, so that upon seeing the graphic representation, people will be able to recognize the criminal. In addition, eyes are crucial in recognizing different faces. Although it is commonly perceived that facial features equally contribute to distinguish people, eyes are mainly foremost. Many studies and researches have been done regarding the magnitude of eyes in discerning between different people. Because of their value in facial recognition, drawing and portraying eyes is crucial, especially in facial composites. A facial composite is a sketch of a face drew mainly from a description provided by an eyewitness. Facial composites are often used by detectives and police. According to a fresh study from a researcher at the University of Barcelona, human brains extract important information for facial recognition principally by the eyes, and secondly from the nose and mouth. More results from the same investigation indicate that images of eyes give the least clustered and noisy result. Also, they convey more reliable information to the brain than when compared to the images of the mouth and nose. This information suggests that the face recognition mechanisms in the brain are specialized to the eyes. Moreover, the most useful information is obtained from the images is their size is around 30 by 30 pixels. Another study revealed that when viewing a human face, people often look toward the eyes. Maintaining good eye contact carries a significant social value and allows for the extraction of information. When identifying faces, people also look towards the eyes, but it is still uncertain whether this behavior is solely a byproduct of the socially important eye movement behavior or whether it has functional importance in basic perceptual tasks. Gaze behavior while determining a person’s identity, emotional state, or gender can be explained as an adaptive brain strategy to learn eye movement plans that optimize performance in basic perceptual tasks. Therefore, when creating a quick sketch to portray humans solely relying on the memory of an eyewitness, it is crucial to correctly display the eyes of the target. If the rendering of the human eyes is incorrect, identifying people off of the sketch becomes incredibly difficult. A forensic sketch artist interviews victims and witnesses of crime in order to gather information about the appearance of the suspect. The most crucial component of an accurate facial composite is the value of an eye witness’s memory. Recounting a person’s face that may have inflicted harm on somebody may be an erroneous process. The memory of a

human can play tricks on a person, amplifying certain details and erasing others. For this reason, sketch artists must conduct interviews very carefully and with sensitivity to extract as many
