A Study of Image Authentication Technique by Applying Fixed Point of Regular Stochastic Matrix on DCT
碩士 === 國立中興大學 === 資訊管理學系所 === 102 === In this paper, we propose a novel method of robust, high accuracy image tampering detection. By using the idea of fixed points extracted from a DCT (Discrete Cosine Transform) coefficient matrix from the field of stochastic matrices, we can modify this fixed poi...
