Juvenile age estimation from facial images

Area of Science:

• Forensic Science
• Developmental Psychology
• Image Analysis

Background:

• Accurate age determination from images is critical in child sexual abuse (CSA) cases for legal proceedings.
• Precise age estimation influences offender sentencing severity.
• Visual assessment of juvenile faces is a common method for age determination.

Purpose of the Study:

• To evaluate the accuracy of visual age estimation for juvenile faces (0-16 years).
• To investigate if varying levels of exposure to children impact age estimation accuracy.
• To identify factors influencing the precision of facial age assessment in minors.

Main Methods:

• An online questionnaire was developed using SurveyMonkey®.
• The questionnaire included 30 juvenile face images for age estimation.
• Participant demographics (age, sex, occupation, number of children) were recorded.

Main Results:

• Overall accuracy of visual age estimation for juvenile faces was found to be poor.
• Participant characteristics and exposure to children did not significantly affect age estimation accuracy.
• Juvenile face characteristics (sex, age) also did not consistently impact estimation accuracy, though sex may play a role in specific age ranges.

Conclusions:

• Simple visual assessment of juvenile faces alone is an unreliable method for accurate age determination.
• Further research is needed to understand facial indicators and features influencing age estimation accuracy.
• Developing more robust methods for juvenile age estimation from images is essential.
