Do photos of the same person show the same ratios? Do photos of different people show different ratios?.Measure features on the faces such as distance between eyes, width of mouth, height of head etc.We also have a Viola-Jones Face Detection interactive available, supporting text will be added at a later date.įirst let's manually try some methods for recognising whether two photographs show the same person.
