I want to apply functions to the (8)bits of pixels of an image. how could i do that with respect to Gray image and also especially with RGB image.
And i need to hide RGB mosaic image pixels inside another RGB target image at specified bits. can anyone could help me!!!

If the 24 bits per pixel are 8 bits of Red, 8 of Green, 8 of Blue, then just imread() the image, as that is a very common format.
I suspect your question is how to convert the data to "binary". For that see dec2bin()

See attached example on LSB watermarking.
