Performance Analysis of DCT and DWT Algorithms in Image Steganography
( Qatar University Press , 2021 , Poster)Frequency domain techniques such as Discrete Cosine Transform (DCT) and Discrete Wavelet Transform (DWT) ensures high accuracy when compared with the spatial domain techniques. Therefore, these image steganographic methods ...
