i'm doing image steganography and i am using DFT to get the coefficient. i have some probelms and questions here:
1. when i'm using fft, the coeffient is in imaginary number. so if i try to divide the value with the value in quantizer table, the number should be still in imaginary. then what should i do to get the real value only to easier for me to hide the hidden image into the coefficient?
2. from the example i've got from internet, they use fftshift and spatial image?
i'm very happy if you can reply my questions. thank you
hello mr. Ankur Pawar..
i am last semester student and i am doing final year project on image steganography.can u help me to hide jpeg image in another jpeg image by using DFT or FFT technique?
