considered is grey scale image. … (IWT) is used to hide secret images in the color cover image. …

… color space for higher capacity rates. … image. Experimental results demonstrate that the
proposed scheme is able to show advantages over traditional RGB schemes in hiding capacity …

… hiding for covert communication is supposed to be accompanied by the attributes like high
data hiding capacity (… The cover images chosen for hiding the data are 512 512 RGB bitmap …

… high capacity stego algorithms can be secure if images are … security to the high capacity LSB

… the secret information into the cover image to obtain a stego image (S) with secret data hidden
in it, we are equipped with the fact that an image has RGB planes. The cover image (C) is …

… We propose to use the YIQ color space model to transform the RGB value of the secret
image pixel into three separate components, which are then embedded into the least significant …

… secret image. We tried to propose a new methodology to hide a color image within another
color cover image … In this approach the imperceptibility and distortion of the Stego image is …

… -image cannot have any distortion, a high capacity distortion-free data hiding algorithm for
the palette image is … If color RGB, is repeated ZL-l times, then we can say that RGB, is a copy …

… To achieve high embedding capacity we propose to use the YIQ color space model and
RGBA based cover image. RGB value’s of the secret image pixel’s is first converted into YIQ …
