摘要
In compliance with the method, the measurement of the characteristic dimensions of the hypothetical pupil are taken on the basis of a sequence of images. The eye is stimulated with the light featuring a pre-defined intensity profile. For each image in this sequence, the characteristic dimensions of the hypothetical pupil are calculated by means of image processing methods. For a sequence of images, the system determines the function f which defines the changes in the characteristic dimensions of the hypothetical pupil within the measurement period, and on the basis of the said changes as well as on the selected mathematical model, the aliveness parameters O of the eye are determined by means of estimation methods. The calculated aliveness parameters are compared with the statistical template by way of classification process.
