I don't think that you use the same algorithm but one that just reverses the steps in the other. Try working backwards from the other code.

Hi, I have done message hiding with image by using java, since I don't have matlab coding knowledge, I will give you the text retrieval from image code in java
int byteCount = 0;
for(int i=0;i<fileBytes.length;i++){
for(int j=0; j<8; j++) {
fileBytes[i] = (byte)((fileBytes[i] << 1) | (colorBytes[byteCount] & 1));
byteCount++;
}
}
