Answer 1

You can just average the images,

markedImage = uint8((single(image1) + single(image2))/2);

though it gets tricky if your watermark is smaller than the image because you have to decide where to place it. You might take a look at Stitch which blends images in addition to stitching them, and handles the size mismatches.

[rows columns numberOfColorChannels = size(imageArray);

middleRow = floor(rows/2);
middleColumn = floor(columns/2);
row1 = middleRow - floor(rowsWM/2);
