I want to hide image under cover image using DCT. But while doing quantization step, most of dct coefficients of cover image become zero . So should i avoid quantization step during image steganography or choose a cover image of much larger size to embed each bit, what is correct method to hide image under cover image using DCT?I want to hide image under cover image using DCT.
