A Robust Image Perceptual Hashing Scheme Based on Improved Normalization Algorithm

摘要：

　　An improved image normalization algorithm is proposed firstly.Then a geometric robust image perceptual hashing scheme is proposed based on image normalization and discrete cosine transform.The original image is preprocessed using our improved image normalization method.And the selected DCT coefficients as image feature are encrypted for security.The geometric robust image hash is achieved by quantizing encrypted DCT coefficients and coding.The experimental results show that the algorithm can resist against common global affine transformations such as rotation,scaling,translation and their combinations.
