This provision does not disrupt the information content of either of the images. Image steganography can lead to a loss of a lot of information. Therefore, in our case, we have stored the first four bits (starting from the MSB) of each pixel in the hidden image in the last four bits (ending at the LSB) of each pixel in the front image. at(j,i)[0] = tHidden_image. at(j,i)[1] = tHidden_image. at(j,i)[2] = tHidden_image. at(j,i)[2] >> 4; } bitwise_or(tFront_image, tHidden_image, aStegedImage); } Code explanation The function which will perform the image steganography is as follows: void steganographMyImage(Mat& aFrontImage, Mat& aHiddenImage, Mat& aStegedImage) This function takes three parameters.

Short comments have also been included in the code itself to increase the readability. hpp" The preceding two header files will be a part of almost every program we write using the OpenCV library. As explained earlier, the highgui header is used for window creation, management, and so on, while the core header is used to access the Mat data structure in OpenCV. using namespace cv; using namespace std; 19 Instant OpenCV Starter The preceding two lines declare the required namespaces for this code so that we don't have to use the :: (scope resolution) operator every time for accessing the functions.

The preceding function takes six parameters, out of which the first one is the variable containing the source image to be modified. The second one is the variable to store the resized image. The third parameter is the output image size. In this case we have not specified this, but we have instead used the Size() function, which will automatically calculate it based on the values of the fourth and fifth parameters. The fourth and fifth parameters are the scale factors along the horizontal and vertical axes respectively.
