Reversible Data Hiding in Image Based on Wavelet Transform
碩士 === 大葉大學 === 資訊工程學系碩士在職專班 === 96 === This paper represents a new approach to reversible data-hiding using discrete wavelet transform in frequency domain.The continuous set of zero coefficient produced by quantization of the coefficients of the wavelet is used to conceal the data. Most of time, th...
