摘要

A rephotographed image recognition method, comprising: acquiring an image to be recognized; carrying out a Fourier transform on the acquired image to be recognized to obtain a Fourier spectrum feature map; extracting an LBP feature value from the Fourier spectrum feature map; according to the extracted LBP feature value, generating LBP histogram statistic data for representing an LBP feature value statistic probability; inputting the LBP histogram statistic data into a neural network model, and carrying out recognition processing on the LBP histogram statistic data by means of the neural network model to obtain a first rephotographing probability; and when the first rephotographing probability reaches a probability threshold value, determining that the image to be recognized is a rephotographed image.
