First, the specificity and permanence of human body appearance are discussed from the integrality of human appearance. Afterwards, the favorable and unfavorable factors in human image examination are analyzed. The study and practices suggest that the overall working process is comprehensive. Sufficient image datum and related evidences are necessary. Various examination technique methods are used synthetically to carry out analysis and evaluation. Human image characteristics can be mutually interrelated, complemented and supported, which reveals the similarities or differences between human features and leads to certain identification or elimination.
