碩士 === 華梵大學 === 資訊管理學系碩士班 === 97 === In this thesis, the embedded watermark using discrete wavelet transformation (DWT) is proposed to convert images into four various frequency sub-bands. Furthermore, Particle swarm optimization (PSO) is used to randomly select any sub-band to adjust three importan...
